SL-C superlite
Anyone have even experience with one? driven? seen one run? Lap times?
Was Looking at one at JDP Motorsports they had in for some tuning, it's just looked like it would be really good on the track build from the ground up as a trackcar with their race cage ect.

Seen one race. Fast lap times with a lots of hp (the SL-C team car to Mid-O for NASA nats in 2011 and the RCR SL-C team in 2012). Just about as fast as the DSR cars at Mid-Ohio in 2012, but the RCR SL-C is a very expensive build (Roush-Yates engine, LMP transaxle, new geometry, etc). The RCR car is at the Thunderhill 25 (going on now).
A "regular" SL-C looks pretty cool. Definitely could get expensive.

The RCR replicas and SL-C are interesting cars, all designed by guys that have racing experience.
They use relatively thick aluminum for the tub, (3/16" I think) and that makes for a pretty robust tub that they can seam weld without a lot of distortion. This cuts the cost of fabrication an awful lot. I would have to think that they are pretty stiff. The cage doesn't have to go to the bottom of the tub, it sits on the side tubes.
The only thing I don't like are the very short upper control arms in the front suspension. I think it can work, but the range of motion in that setup has to be pretty small. I would have to think that the ride height setup range is pretty small, and if you got too much roll the geometry would go to hell in a handbasket. If you put pretty stiff anti-roll bars in it and stiff springs and shocks it could work, but they really traded foot room for poor geometry and I think that might not have been a good way to do it.
Other than that, I think they are pretty neat cars and with a big power LS motor they would probably be a heck of a track day car.

From what I have heard from a guy that tried to build on for the road these things are race cars that take a hell of a lot to make road safe! If the car is just for the track then these are probably a good choice, although as said very easy to get expensive.
If you want a more road orientated solution the UltimaGTR is a great choice that can be built to be VarRY competitive on the track!

Here is a link to their web site that shows their suspension pieces. Look at the second shot that shows the upper front control arm.
http://race-car-replicas.com/rcrsuspension.html
The front upper control arm is maybe 6 inches from ball joint to the pivot axis. Probably to be similar to the front, the rear also has very short upper links. Like I said, if you severely restrain the travel (like in a race car with a really stiff setup) you can get away with it, but you really don't want to do that with a dual purpose car. Super high spring and shock rates tend to make the car skitter a lot unless there is a lot of downforce present,
You'd like the arms to be twice that for the geometry to keep the roll center from moving from side to side and up and down an awful lot...

I would be building it for a track/race car and primarily for Miller which is a pretty smooth track. I have called Fran the owner about ordering a kit, 6 weeks out but I didn't want to miss the whole spring trying to get it together. Would like to find one for sale that is complete.

I'm three quarters of the way finished on my SLC build. The plan is for street driving with the odd "track days".
I'm using a Corvette C6 gauge cluster, hud, bcm and interior wiring to give it a production car feel. The engine is a LSA block (for the piston oil squirters) and is now a dry sump 427. The transaxle is a Ricardo (used on the Ford GT). The tires and wheels are standard Z06 size. I added side marker lamps, a third brake light and license plate lights for road use. I didn't take the factory wiring. Instead I have replicated a complete wiring system from a C6 Corvette. The C6 Z06 headers and cats are in use as well as the complete EVAP system. Even the C6 fuel fill pipe and cap are used to make it easier to meet registration rules. Five point seat belt harnesses are illegal in my Province so a standard three point system was fabricated.

I know Fran (owner of Superlite/RCR) personally and he's a great and super knowledgeable guy. I've been to his place a few times and his work is top notch. The SLC is an incredible bargain for what you get.
At Thunderhill, though teams have had various dumb failures, the car absolutely dominates the unlimited class. PDG has developed their GTM for years, and while they tend to have more bugs worked out for the 25hr race, the SL-C's spank their *** all over the track...the small teams have just had bad luck with things like steering racks and axles, etc. In terms of the chassis though, there just isn't anything in the price range that will touch it on a track shy of maybe his new car that he designed after the LMP Cadillac (he worked on the Cadillac team and has the original molds I believe).
