New here, and seems to be the place to be....
Short history, started HPDE last fall at NJMP,
After 10 days went and bought a
1998 Trans Am, which was built by Wheel to Wheel in Detroit,
ran Motorola/Rolex GT 1998-2002, then became ITe/AIX car.

Now it's a HPDE /Track DayCar
THat I am TRYING TO SORT>>>>>>>>>>>maybe TT in the future..

MAJOR ISSUE: BRAKES SHI**TY............Must hit pedal 2x's to set up for turn....
Specs:
1998 Trans Am / 392 RWHP LS6 / Son of TransZilla T56 (yea that was a 5k mistake, visit that later)
SLP Konis, rear adjustable seats, Front NASCAR sway bay, Rear Blade Sway Bar
17x11 CCW275/40 17 R1's

Need insight on how to make this car brake as well as my 13' 1LE Camaro
currently , WW 6SLR fronts, new rotors, new hats, PBR rears
Corner balanced to 49.8 % a week ago, (still LF ride height 3/4 lower, so I screwded up
my first attempt!!!)
Car has proven history,
looking for insight on how to make right!!
Thanks from new guy,
Rich

Was going to look into watts conversion, but the car has lasted 16 years this way



that is not a good philosophy if improving your car is the goal (IMG:http://www.frrax.com/rrforum/style_emoticons/default/smile.gif)

Probably misstated..
YES , I will always look to improve the car. Watts is in reality low on the list..

#1 Fix the brake issue!,
after research it turns out the car is equipped with 93-97 LT-1 Rear brakes and calipers.
( goes to statement our current rears are sufficient)
COntacted Wilwood, they said no way should I use their rear setup
Contacted Kore3, they said I could order a c5/or c6 rear setup,
would take about 4-5 weeks, and would require axle removal, as the current
LT1 mounting plate is different than the LS/C5/C6 plate.
THey were very helpful, and honest, and reco'd just get a rebuilt caliper for the left rear.
PBR does no longer manufacture LS calipers, so rebuilds are your only avenue.
Overall very helpful.

#2 HANS ( or other if anyone cares to provide better insight,)
and did I make a mistake by getting 3" Shoulder harness set, and will a HANS device work with 3" shoulders"

#3 Learn chassis setup, tweak sway bars, tire pressures, ride height, and corner balance...

#4 Support daily track day consumables, visit other tracks, find a good group of friends
with the same interests, ( surely appreciate everyone here's input")

#5 Now spend $ for .10 sec improvements...

The 94-97 rear brakes are the best rears for the 4th gen - the builder probably replaced the 98-02 brakes because they are heavier, and if the Pbrake drum is left in place it can seize up.
Get a set of Centric remans, and Centric rotors, all 94-97. Your backing plates have been changed to accept the early brakes, don't try to put late stuff on it. The early calipers had a weight attached to them for NVH, the remans will not have the weight - don't worry about it, we toss the weights anyway. Make sure you get the 94-97 pads - 93 are different.

If you go with C6 front brakes get the Trackbracket package from Hotpart, it's better than the others. Use plain Centric base C6 rotors.

HANS will work with the 3" wide harness, tho 2" fit better, both lap and shoulder. Look at the Schroth Profi II HANS - my standard rec.

Halo seats - Racetech RT4009HR, or the wide model, if you have the budget. Kirkey K68 or K45 fit a more modest budget.
