Well I am new here and I am looking to run at summit point. Really I just want to know where to start.

The main car I am looking to run is a 91 Z28 heres the specs:

-195CC Aluminum heads 5 angle, polished, etc...
-Brand spanking new 350
-LT4 Hot Cam
-Alum. 1.6 Rockers
-3.42 Posi Auburn Rear
-Stock TPI intake
-Poly Bushings
-TDS Wonderbar

I am working on the following:

-8 Point Roll Cage
-Spohn Tubular K-Member and A-Arms
-1-5/16" front sway bars, and 1" Rear.......Would this be ok?
-Aluminum Driveshaft
-T56
-13" Corvette Front brakes
-Y2K C5 5 Spokes
-255 Fronts 275 Rear Undecided on tires..... Any recommedations?
-Wilwood 12.19" rear brakes.... anything out there better?

As for the rest of the suspension I am looking for more suggestions.

I also have a 98 Z51 thats holds the garage floor down and a 91 RS which is my daily driver.

As for summit point where do I start? Who do I contact? etc.

welcome to the board. hope you like it here.
btw, on the items you are working on, the k-member, i strongly suggest you do some readings on the board and check about the new UMI K-member that seems to be very strong and much more oriented towards racing (not just 1/4 mile)
Also, for any fab work for cage, BlaineFab does excellent work and can give you lots of great advice.

As for the sway bars, not sure about 3rd gens... but you are thinking 33mm/25mm setup. for a 4th gen, that would make the rear a bit loose.
As for the brakes, the rears aren't worth the upgrade... put the $ on the front ones... and good pad selection.

Welcome aboard and enjoy the reading and the fun.

I didn't think UMI made a K-Member for 3rd Gens.

I just read that they are working on it. Sounds great.... I like UMI because it seems they aim for road racing not drag queens.

What else should I look into? Lower LCA brackets? coil over kits?

My goal is to be competitive with a 06 Z06 handling wise. Engine wise.... I will figure out when I can.... maybe a 427CI LS2? (IMG:http://www.frrax.com/rrforum/style_emoticons/default/biggrin.gif)

I am a novice but not stupid. I have my associates in engineering and working on my bachlors. Graduated high school at 16. I am currently 19.

So really lay it on me. After I really start getting into this I wouldn't mind getting something I am not afriad to mess up and rub some tires.

I have a friend who is actualy with me for the ride with a 87 Iroc Z28 with factory T-Tops.... I know hard to beleive but no joke lol. His name is Shlomo... I know seriously though. My name is Mike by the way. Sorry for rambling lol. (IMG:http://www.frrax.com/rrforum/style_emoticons/default/1poke.gif)

Graduated high school at 16.

First off... Overachiever (IMG:http://www.frrax.com/rrforum/style_emoticons/default/tongue.gif) But having just graduated as an ME after too many years of trying, keep it simple until you're done with school. I can't remember how may autocrosses I've missed because I was trying to get the car ready while doing homework at the same time.

The best thing is to get the car reliable and predictable before any major work is done. It sounds like the motor is already in, if so you know the factory TPI leaves some power out there. Aluminum rockers are nice, but may not be the best choice for longevity. Keep an eye on them.

WS6/Z28 factory swaybars are 36/24mm. I found that with street tires this combo oversteers quite a bit, but with R compounds it pushes slightly. Try what you have and adjust as needed. For the brakes, factory rear disks should be fine. '89 and newer rear disks are almost the same as LT1 rears. I think the difference is rotor height and a noise damper on the caliper. Again, try what you have. By working your way up to the corners you sahould find the limits of the brakes without getting into too much trouble.

LOL!....

School is no burdon at all. I well be doing like 2 classes at night during the week. I like the job I have now so I am not planing on leaving it just looking for more education. Within a few months I should be getting another raise so I will have more funding. (Most people think I have to much now).

I am trying to go all out but I don't want to do it all at once because I would like to see what I need to adapt to my driving.

But I do want to buy everything I can that has nothing to do with my driving that helps the car.

So like would lower lca bracket help? Tubular panhard bars, LCAs, etc.

I am deffinitly going to go with a UMI K-Member and A-Arms along with there SFCs. I have done alot of structural CAD and I tell you thats amazing stuff they have over there compared to everything else out there.

Also with me going with a tubular front end and using aluminum heads I am pretty close to pulling 100 pounds off then front. What can I do to compensate for the ride height? Is there like an adjustable coil over system out there or something like that?

Tires.... anyone recommend a tire that wont kill me everytime I have to replace them? Id like to do 275s all the way around after reading what you said about tires being equal. Would that work ok?

I do have a LT1 rear in the car now with a disc rear. You guys are saying it will "Work". Can I improve at all apon them?

Rack and Pinion and power steering...does anyone make an aftermarket one that will tighten the ratio up and just the overall steering?

Brake Booster and Cylinder... anyone make an upgrade for this?

Will the 3.42 rear gear be ok at a track like summit with a T56? Should I go lower? or even higher?

Sorry for all the questions...I just love to learn (IMG:http://www.frrax.com/rrforum/style_emoticons/default/nutkick.gif)

PF Flyer your local... didn't notice lol. Anyway I can check out your car sometime? Also why don't you come to any of the local events? lol (IMG:http://www.frrax.com/rrforum/style_emoticons/default/twak.gif)

Be aware that the 17x9.5 with 5.5" of backspacing will not fit that axle, you'll need to adjust the backspacing for the extra width of the axle (don't just order the wheel sizes I gave you since you've changed axles).
