Not seeing that on Carlyle's web site.

Baer has bolt on brake kits for the front and rear of the S550 Mustang platform, that allow 15" wheels front and rear. Baer's kits are about $900 per end, and the rear one has no provisions for a parking brake. They claim their brake kits will save a bunch of weight. I think these cars will comfortably run under their current index(es) with the stock brakes (although I would avoid the Performance Package car because of it's even larger front brakes).

Alan's probably got the right idea- a set of drag radials on the stock rear wheels, an off-road down-pipe, a "tune", install the required safety equipment, and it should run under anywhere.

Well, if that is the case, then a substantial HP rating is clearly needed. Stock Eliminator is not supposed to be that "easy".
Or, at least it was not, before all the new corporate "package" cars came into existance.

Rory's right here. Don't forget , 3 tenths came off the indexes less than 10 years ago, too.

Jim Bailey is also right. We know what will happen to this combo in the next year and a half.
So, if anyone is going to do it as a street car...get off the pot, as they say.
Then let us know if you can cut a light and run within 5 hun, back to back. Anxiously awaiting the results.

Half a second away from the K index with drag radials on stock wheels.

I didn't hear them say what octane fuel they are running.That makes a huge difference in the tune. Most likely it has stock rear gears.

I would say that car is probably at the heavy weight limit for K

Yeah, that's a Performance Package car. They come with 3.55 rear gears instead of 3.31, larger/heavier front brakes, 19" wheels instead of 17" wheels, and some other doo-dads.

.33 off the K/SA index. With an off-road down-pipe and no exhaust system, that car would probably be under index.

Does it need a roll bar for K/SA?

I am just trying to get this whole conversation clear in my mind, is this being proposed as some sort of cheap and easy way to build a Stocker (which it absolutely won't be)? In my mind there are an infinite number of better and cheaper ways to approach Stock class if that's the plan, buying someone's complete finished car comes to mind. Or is this just some sort of philosophical debate (which often happens on Class Racer)?

I'm sure you guys know what you're talking about, and I'm not going down that road if the impending "Baby Jet" is going to make it impossible for me to continue.

Nobody said it would be "Impossible to continue", it just may require you to spend some money and do some work, just like all the other Stockers have had to do for decades.
