944 spec uses a rather basic suspesion. More similar to IT and PCA stock class, but still not full up IT car.


Rules are such that you strip the car and are allow a few more things to pull. Weight is 2600lbs with driver so it is a bit higher then the new IT limit. Given the more liberal stripping rules it should be easier to get to weight in a 944 spec car and should not need to strip it all the way down complete.


Engine prep rules are very limited. The intent is to have Junkyard motors running at the front. We achieve that now. We don't figure in a 25% power gain. More like 5% powergain as most cars are 128 to 135rwhp.

Suspension rules don't allow metallic bushings/bearings etc. Only stock rubber, polygraphite or delrin. Rears are limited to 30 mm t-bars which comes to 335lbs-in. That limits front spring rates to the 250 to 450lbs-in range. Shocks are limited to off the shelf koni yellows and bilsteins.

Wheels are spec to two forms of stock wheels and tires are spec at 225/50 R15 Toyo RA-1's

BTW...We came to 2600lbs as a min class weight with driver by taking weights of a few stripped 944's. Seemed at the time like most cars and drivers could make 2600lbs by just taking all the stuff not needed for racing out of the cars. Over the years we have some cars below the 2600lbs ( for example add 40-55lbs of ballast) and others seem to struggle a bit. Given that 2600lbs seems like reasonable weight that can be easily achvied by most, but at the same time allow the cars to be fast and fun. It is interesting that the ITAC came to 2575lbs as their class weight as it very close to what we figured in as the ideal comproise between fun and cost.

What I can tell you is that a fully built 944 spec car is still too slow for ITS. Even at 2600lbs the car is better suited for ITA given the limited engine prep and suspension. Assuming you can get 20% more hp from the car and do a bit more suspension work it might be ok in ITS.
