Was that question for me? I live in S. Florida (although I grew up in Philly!!)

SP1 cars are lot more equal, but are NOT softly sprung. If driven on the street they are so stiff as to be tolerable for only a short distance. A stock 944 NA suspension has several times the body roll of 944 spec car. Infact any street able 951 will be infact much softer than a properly built 944 spec. While we use 250 to 400lbs front springs the cars are some 700lbs ligther than my stock 951S. (2600 with driver vs 3300 for my 951 S) That 700lbs makes a HUGE difference. One could go much stiffer, but then you'd need to invest quite a bit more cash into proper racing dampers and that just increases the cost by a large margin with small increase in performance. Once you are racing you'd never notice the difference. In fact most lower priced SP2 cars will be using a 944Spec type suspension, but will be carrying more weight.


All 944 spec cars use the same 2.5L 8valve engine and run 2600lbs. 944 cup allows 3 different prep levels at different weights. They run tires from 15" to 18" in diameter and weight range from 2650 to 3000lbs all in the same class. Dave has done a nice job of balancing the prep levels, but it is not a spec class by any means.

944 spec was designed from the start for low cost, fun, equal racing of the 944 NA so there are no rules compromises.

Body Roll comparison

Picture 1 look at the red/white 944 spec car


Compare to the heavily prepared E46


Same track, same corner. Both cars turing race laps. In the 944 this is flat out mid 3rd gear. In E46 this probaby not flat out, but the driver would be on the limit.

Thanks Joe. So the specs are not like the stock F class pca club cars. Can you use camber plates?

LMAO....right before the E46 M3's motor did this:

M758

944 Spec allows camber plates, but limit the rear spings to t-bars only and 30mm max. So overall the spring rates are not super high, but due to the lighter weight a well driven 944 spec car will be only slightly slower than average F car. In fact our best driver tan #99 used to drive a F prepared 911SC. He sold it got the 944 spec car and runs about 1 second slower lap that he did in his 911.

Thanks Joe. So the specs are not like the stock F class pca club cars. It is very true how significant weght is to a cars handling. With a 700 pound weight reduction and 300 pound linear springs, I can feel the concussion now, driving on public roads. So shocks, springs, bars, strut brace and camber plates can be used in SP1?????

Yep,

Now back to or regularly schedure TD schooling!

TD in DC

Usually when I get schooled it is on the track

Renvagnm,

944 Cup cars have the same basic rules as PCA I stock or H prepared - so springs/shocks are free. F cars run in the Supercup. Also, ITS prepped cars can run in cup with a small wieight penalty due to their increased hp level.

Cup runs primarily with Nasa in both the Northeast and Mid-atlantic - which means, watkins glen, mid-ohio, summit point, VIR, Beaverun among others. Typically you'll see 20-30 car fields at most races. As we're hijacking the hell out of this thread, PM me if you'd like.

And now back to our regular scheduled programing
