Default SCCA CAM S What are you running?

I saw some early chatter right after the rules were released about a few folks that were planning to join.
I thought it'd be fun to get some of the cars/drivers/mods all in 1 thread and then as the season goes on maybe we can put some screennames to faces!

I'll start:

2002 C5 Z06 I'm teaming up with Ryan Finch as a codriver for most of the midwest events and nationals. Hoping he can actually show me what the car is capable of:
http://bangshift.com/bangshiftapex/b...ptima-detroit/

Suspension:
Ridetech HQ single adjustable shocks
Ridetech Delrin Bushing Kit
Stranoparts front/rear swaybars
Custom endlinks

Brakes:
Wilwood Forged Superlight 6 piston front, 13” or 14” (rotors event dependent)
Stock rear

Wheels:
18x12 & 18x11 Forgestar F14’s
335/315 BFG Rival S

Engine:
Lingenfelter Built Crate LS7, Low compression configuration, 499whp/464wtq


Transmission/Differential:
RKT Built T56
Stock Differential

Why can't you run a Rival S in 315 or 335 on a 12" rim?

That looks like it must be a handful on the auto-x course!

where do you typically run?

I'm sure I'll do a few with my stock suspension, PSS street tire turbo setup. It'll be horrible.

I am very possibly in for CAM in the near future. Like Brian, I will have to buy a set of 18s and some proper tires if I take the leap. 96 C4, 396 LT4, VBP Xtreme springs, rear anti-squat relocation brackets, and some other suspension and brake stuff. Full interior, full weight, a true street driver (been my daily driver for the past three weeks while I fixed my true DD).

My only other real option in SCCA classes is SSM, and that pax is much worse and I'd need A6s. That means a tire trailer and changing tires at the event. I'm not sure I'm up for that these days. CAM S seems more suited to my car and me. I'll just have to resign myself to the idea that a much faster Vette could show up, and if any Cobra shows up (350lb weight break for that!?) then I'm automatic toast. But hey, for now it's just about fun for me (it's been almost eight years since I last competed, so we'll see how long that just-for-fun thing lasts).

ETA: This will be in and around the St. Louis area.

Cobras are beatable. I've been as close as .3xx on an 80+ second course to Scott Fraser, the current CAM-S national winner. C4's are better suited than the c5's. Just gotta work at it.

Would be cool if we could provide state/region too so I know who I'm going to run into

What offsets? Same size wheels I went with. Any cutting or sticking out past the fenders?

Given the variables of driver skill, any car is beatable. But if you're comparing a 3300lb C4 to a 2650lb (ballasted up) Cobra with rearward weight bias, then that's a huge advantage to the Cobra. Given equally talented drivers, the Cobra is an easy pick. The reality is that I'm not gutting my car enough to even get down to the 3000lb minimum for Corvettes. But even if I did, it would be tough to beat an equally prepped Cobra.

I'm curious why you say the C4 is better suited. I'm not sure one way or the other, so I'm really asking. I know the C5 can easily get down to 3000lbs, which is an advantage over a C4. The C4 has a much shorter wheelbase, which may benefit autocrossing. Can you expand on your thoughts about this?

The other issue is the Cobra he's talking about also has 850 HP and a lot of other mods.

I've seen the vids. I'm convinced the power is almost worthless at autocross speeds over what I have (I have maybe half that or a bit more at the wheels). But yeah, Cobras are an almost blank canvas for almost any suspension someone wants to run. And that certainly can make a difference!

We do all realize this cobra in question was raw timed by AS, right?

The shorter wheelbase is the main reason, the abs is less intrusive and doesn't it also have a narrower track?

Back when we were running BSP our C4 was about just as fast as a super stock C5Z.

With the "no rules" of CAM you can get pretty much anything you want, but you'd have to do a lot of work to make a C4 as fast a stock C5Z.

If you go to an LS motor to get the weight out of the front of the car, strip it ll down, put light weight hood on it, stiffen the frame rework the rear suspension it could be faster, but for all that work you might just as easily buy a C5 and have a much better platform as a starting place. John Carriere had the data on how much the front frame on the C4 twists and the amount of camber loss that is there is really amazing. Not saying you can't do it, but it's going to be a lot of work.

We got our BSP car down to about 3100 lbs so if within the CAM rules (or lack of same) you could probably get down to the weight limit. And yes the wheelbase is shorter and there are things a C4 will do that you can't do in a C5, but I don't see that for an equal amount of work the C5 is probably going to be any faster.

Of course If you jack up the VIN plate and change everything under it you can get there, but at what cost of labor and time?

The real key would be to get more than 50% of the weight on the rear wheels and I don't know if you could do that with the weight of the C4 platform.
