AST Driver sweeps NASA CMC Event

Posted in AST Suspension, Industry News, Products, Uncategorized, Wins on March 18th, 2009 by admin-ast – 1 Comment

In his debut event on AST 4100s, Jeff Wirtz of Round Rock, TX pulled off a sweep at the NASA event at Motorsport Ranch.  Jeff was always a top finisher last year, but with ASTs on the car Jeff put multiple seconds on the field in 4 of 4 races.  This included inverted starts where he passed the whole field in the opening laps!  The only car faster than Wirtz’s 3rd Gen Camaro was a fully prepped Mustang AIX classed car (a much faster class). 

Camaro Mustang Challenge is a popular class in NASA that is growing especially in the Texas Region.  Wirtz was able to drive a competitor’s car in practice, a car having twin tube shocks.  “I felt bumps on the track with the twin tubes that I didn’t even know were there with the ASTs,” said Wirtz.  AST’s monotube technology can provide forces greater than many lower end shocks without the harshness most drivers experience.

Congrats to Jeff in his first event with the shocks.  Stay tuned for the April event at TWS in College Station!

RRT Suspension wins on AST 4200s

RRT Suspension recently made their debut event with their "do it all" BMW E36 running AST 4200s with Vorshlag camber plates. The 325i was built specifically to compete in NASA GTS 2, SCCA ITR, and BMW Club Racing Prepared class. The "do it all" car came out fighting last weekend at VIR. Due to an issue with qualifying run groups, RRT’s Barry Battle was forced to start in the back. Their forum has a video of the 10 lap race where Barry passes the entire field in the first 3 laps and then puts 40 seconds on 2nd place by the checkered flag. The car looks hooked up once he gets through the crowd. We think that must be a combination of driver and suspension since the car has the originally 200k mile motor in it! Great run Barry!

Update on Evo X suspension

Posted in AST Suspension, Products, Tech Articles on December 23rd, 2008 by admin-ast – 2 Comments
Quick update on the Evo X suspension.  We’re waiting on rear top mounts to test with the rear suspension, but we had enough time on Friday afternoon to get the fronts on. 

We installed our new camber plate and AST 4200 double adjustable shocks.  For this first install we used Hyperco 7″, 450 lb, 60mm ID springs.  Not sure where we’ll end up but that’s where we’ll start.  The AST 4200 is an internally adjustable, monotube, nitrogen charged damper designed to meet rule requirements where external reservoirs are not allowed.


The spring perch was moved up to almost seat with the spring platform when installed.  This lowered the car approximately 1″ from stock.  I didn’t want to lower it too much with stock height still in the rear.  We’ll finalize various spring height combinations depending on what dealers and customers ask for.  Yes, we’re aware of driving with such drastically different rates and how that affects handling, ride, etc.  This is just to test fitment, etc.  We’ll put the package together and head out to the track over the holidays if all goes smoothly.
We drove the car over the weekend, granted all the testing was street driving on 5 clicks from full soft rebound, 0 on compression.  We have 12 clicks total rebound and 12 clicks compression.  The car rode extremely well passing the “spouse test” with flying colors. 

Here’s where it sits at the moment.  Lowering the front really helps visibility.  The Evo sits up so high, us shorter torso folk can’t see over the huge, flat hood.  :)



AST 4200s Compete in 25 Hours of Thunderhill

Congrats to the Castrol/Speed Trapp Team for running AST 4200s on their BMW 3 series. The team posted the 2nd fastest lap time in their class but unfortunately had unscheduled brake wear stops putting them back to 6th. Anthony Zwain states, “The AST’s worked great and lasted the entire race without an issue, thanks! There was only one other team (the class winner) faster than our car. They had another company’s triple adjustable shocks and spent about 3 times what we did in car preparation.”

AST Wins at NASA Championship

Posted in AST Suspension, Wins on September 16th, 2008 by admin-ast – 1 Comment

Well, we’re back from NASA’s Championship at Mid Ohio. First off, NASA announced that next year’s Championship will be at Miller Motorsport Park near Salt Lake City, UT. That’s only 1400 miles for us in Dallas, Texas. The event started out a soggy one. Most TT drivers didn’t bother running on the wet days since the best lap counts. But luckily, things started looking great Saturday and Sunday. The track dried Saturday and afternoon run groups had a clean, dry track. Conditions stayed good through Sunday as well if not for a little WIND. Can you say Ike? Yes, even Ohio is not immune to tropical depression winds. I saw more than one canopy go into retirement for this race season.

AST customers sponsored by Elephant Motorsports and Matthew’s Auto Sales brought the hardware to Mid Ohio in the form of AST 4200s and 4300s mainly in the GTS category. Special thanks to the crew at RRT for letting AST hang out at the compound as well. RRT is in the process of building a GTS/ITR/J Prepared car using AST 4200s. The car debuts next season.

In the end, Scott Berkowitz took home GTS 3 in a BMW M3 running the Vorshlag/AST 4200 suspension kit. Scott beat most of the field including GTS 4 and 5 cars (faster cars) finishing 5th overall in a field of 47! Shea Burns, John Van Houten, B.J. Farmer as well as Vorshlag customers Andy Watts and Barry Battle running Vorshlag camber plates all gave it their all this week. Andy took the GTS 5 win and overall GTS category win. Congrats to Andy! RRT brought several cars to the event with top finishes running Vorshlag parts.

Thanks to all our customers who took the chance on a new product and showed the competition what we can do.

We’ll be attending the Texas Region NASA event at Eagle’s Canyon with the Alpha car and our new Evo X in TTB.

As I write this, Terry and Amy have finished their first practice day at SCCA Solo2 Nationals. Terry was running strong in XP with our 4300 shocks while Amy was hanging with the STS Open top drivers in our 318is with custom 4300 shocks. Both cars are handling extremely well. Other AST cars at Topeka include an A Stock WRX STI, a DSP Impreza 2.5 RS, a STX E36, a STU WRX STI, and an XP Miata (our first Miata application). We’ll provide more of an update later this week. Stay tuned!

Vorshlag completed the final testing for the SCCA Solo2 Nationals this weekend. All systems are “go” including the AST 4300s keeping the suspension stuck to the ground. Good luck Vorshlag!

Vorshlag/AST land an Evo X MR!

We asked ourselves, are we crazy? Surely this can’t be done? But what if it could? What if you could daily drive your autocross car, your track day/time trial car, AND have it be spouse and family friendly? No, that is definitely crazy!

Sure, most of us can get by. We can make sacrifices. Heck, I drove a ‘07 STI around town with a side pipe and no muffler all for the “sake of winning”. The downside? Well, no one would drive with me, but sometimes that’s good. Hey, it was light! We’ve all driven cars with 750 lb/in springs and twin tube shocks on the street because we couldn’t afford a truck and trailer. No it doesn’t ride THAT bad…does it? We’ve pulled the A/C out of cars in Texas to drop 30 pounds before a big event. The list goes on and on. You know who you are.

In this time of high fuel costs and tightening spending, we believe the trend of multipurpose cars will become more and more important. With gas over $4 per gallon in some places, you begin to feel the crunch when you tow a car 1400 miles to an event. When the pump shuts off at $100 and you haven’t finished filling up you begin to ponder, is there a better way? I don’t think as “car guys” we’re about to roll over and pick a new hobby. Sure, basket weaving is relaxing, but nothing compares to wide open throttle acceleration or making yourself keep your foot down through a 100 mph corner hoping it sticks this time. No, not many hobbies compare to cars. We want to have our cake and eat it too.

So, if we could find this “car nirvana”, what would it be? What would it look like and what classes could it run in? What are some nice to haves? Lists are subjective, but we had some ideas. It needs to be a smaller displacement motor so probably turbocharged. It needs to have 4 doors, gotta carry people too. All wheel drive could be nice, how many times do you lose in the rain? It happens when you bring a two wheel drive car to the event ask me. One problem though, we LIKE the way rear wheel drive cars handle. Of course we want to make parts for it so it has to have a little “left on the table” from the factory to improve on. It needs to run on street tires. Forget towing a tire trailer and changing tires at the track. We’re lazy and 18″ race tires have gone from pricey to astronomically pricey!

That starts the conversation and narrows it quickly in our minds. Street tires – SCCA autocross has some very nice street tire based classsing structures. We’re familiar with that. NASA TT has some nice classing as well that accounts for treadwear. A plan wouldn’t be complete without hoping to run One Lap of America and a return trip to the GRM Ultimate Track Car Challenge to boot! Don’t forget Redline Time Attack and Super Lap Battle. All possibilities.

Again, this may be subjective, but we think we’ve found a car that can check all our boxes. Friday we headed over to Don Herring Mitsubishi in Irving, TX and test drove some Evos. By Tuesday the next week, we picked up our 2008 Mitsubishi Evolution X MR in Wicked White as they say. You might say, “yikes, but you didn’t factor in price tag?” Yes, the price of entry into the Evo is a little steep, bordering BMW levels. But if you step back and look at the package (and magazine articles) the Evo is a relative bargin to the cars it gets compared against. All the major magazines have done “track car” articles and the Evo is coming close to cars that start at $25,000 MORE than the Evo. It has brakes, power, suspension, and again, checks off our wants and desires. Better yet, it leaves room for improvement on suspension and power! But what about fuel mileage? More on that later. We plan to improve the abysmal mileage the Evo eeks out.

In short, we’ll be combining the strength of Vorshlag and AST along with a few key partners to build what we feel is the Ultimate Dual Purpose Car, Project UDP. Short term planned mods include Vorshlag camber plates, AST 4200 coilovers, turbo back exhaust, and ECU tuning by Cobb Tuning. Stayed tuned for more!

Ready for stickers….
