C4 Track Car
I have a C5 and love it, but with the prices of the C4 I have gotten to thinking about buying one as a dedicated race car (I’m about 3 miles from Summit Point). I’ve always loved the look of the C4, & I’m trying to talk myself into something 
So what would be needed to make a decent HPDE car of the C4? I’m thinking wheels & tires, roll bar, lighter seats, oil cooler, new shocks or coilovers, what else??

With the prices now they are great race cars. I would upgrade the sway bars, new poly bushings, coil overs, strip the interior, put in anaolg gauges, Drive shaft hoop, oil cooler, targa brace, and cutom roll cage. good luck

Just to get out there and run, track pads and ducts would be first on my list. I run at Road America though, which is tough on brakes.
If you like to tinker around and are staying with just HPDE then the sky is the limit. Mod to your budget and preferences.
I've been slowly working on mine and love track driving!

depends on what year it is. But Catless exhaust with lt headers would save weight and make power. lexan top if not a vert. There is a huge variance in springs so coilovers may or may not be needed. Some of the stiffer springs would really be nice with an adjustable shock. However, Coilovers hands down will make front ride height changes less painful and precise. I still have not selected my coilovers but I am getting closer.
R compound tires with so lightweight wheels. c5z06 wheels are or zr1 a molds. Dont buy replicas because of the weight issue. if you get a really nice wheel, it can always be used on both cars.
New upgraded bushings everywhere if they are rotten.
Gears?
Just a few to get started. I am building an 88 track car. I am focusing power last, weight and suspension first.
just some starting points.
There is an endless amount of mods for a c4. Choose wisely as you mentioned "prices"... Very easy to sink a c5 into a c4
If you are a power junkie, you do have an ls1/6 to work with in the c5.....

The new tapered bearings should hopefully fix that issue.
Try to get a 6sp car.
L98 are great autox cars, lots of low end torque, so either get a miniram for it or get an LT1 or LT4 car. These will also have the large brakes and a stiffer chassis.
Here's a good primer for making a C4 track car, and then you have a series to run in.

There's a few track prepared cars already for sale.
You can save a lot of $$$ by getting one that's already setup.

Buy the newest lowest milage one you can afford. Then take it to the track There's lots you can do, it just depends on where you want to end up. Its always easier to complete a journey if you know your destination.
C4s are much cheaper to buy and mod than C5s, but you'll have to put money into the engine to keep up.
Have fun, Paul

Bud, since you live in Berryville, stop by Summit Point (main) on 23/24 August. NASA is having an event there and I'll be there instructing with my C4. Stop by, introduce yourself and I'll be glad to share with you any information I have about it. I've been tracking my '93 since 2000 and can provide some do's and don'ts that might save you a few bucks. As Slalom4Me pointed out, there are quite a few great deals on track prepared cars and RafteRacer's is one.
BTW, I usually paddock near the fenced "corral" by the restrooms. Look for a red C4 #56. Take care. --Ralph
