dbtk2 Posted August 22, 2003 Report Share Posted August 22, 2003 What is the difference between the Generation 1 chassis and the Generation 2? Are all of the aftermarket Gen. 2 sway bars, trailing arms, strut tower braces, etc.... compatible with the Gen. 1 or not? If not, are Gen. 1 sway bars, trailing arms, STB's, etc... available for the Gen 1. Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted August 22, 2003 Report Share Posted August 22, 2003 Everything is different except the trailing arms. Quote Link to comment Share on other sites More sharing options...

90TGP Posted August 22, 2003 Report Share Posted August 22, 2003 i thought the Police package Impala front swaybar fit the firstgen W-Bodys. Or at least that's what I heard. Quote Link to comment Share on other sites More sharing options...

Yeah, thats that GMPD strut bar everyone is getting. Dbtk2, Addco makes a 7/8in rear sway bar. The biggest front sway bar there is (to my knowledge) is the FE3 34mm bar. You can make a rear strut bar, I did, its pretty easy. Robby Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted August 23, 2003 Report Share Posted August 23, 2003 No, the sway bars don't fit gen 1 W-bodies. The police package sway bar you heard about is probably the LUMINA police package bar, same as the one used on all 3.4 DOHC W-bodies (and also all B4U Grand Prix's). The GMPD strut bar only fits because it's a simple bar with 2 holes on either end. All the aftermarket gen 2 bolt-on strut bars do NOT fit.

mfewtrail Posted August 24, 2003 Report Share Posted August 24, 2003 wasn't there something about TGP front sways being smaller than the 91+ FE3 cars front sways? something like 30 or 31mm compared to 34??? I guess I'll measure my cousins 34 mm GTP bar that's still sitting in my garage and the one on the TGP if I get a chance to sometime to rule that out for good.

90TGP Posted August 24, 2003 Report Share Posted August 24, 2003 TGP bar is 30mm while the FE3 bar is 34mm. Quote Link to comment Share on other sites More sharing options...

Chris A Posted August 25, 2003 Report Share Posted August 25, 2003 I don't know if he is on the boards or not, but Joe Grenda recently did this mod and he stated the 34mm upgrade is not worth it. The difference in handling is negligible with stock rubber bushings. However, upgrading to urethane bushings did make a difference. So go bar hunting if you wish. However, as I understand it, the 34mm bar is difficult to fit with urethane bushings and won't provide much improvement. Quote Link to comment Share on other sites More sharing options...

When I had my subrame replaced, I was able to get one with the 34mm bar (I had stock FE1 bar). I already had my front STB at the time, and the 34mm bar (with rubber bushings) made almost zero improvement. Now, my front and rear STBs combined did tons for the car Robby Quote Link to comment Share on other sites More sharing options...
Chris A Posted August 26, 2003 Report Share Posted August 26, 2003 Nuf said, spend your troubles elsewhere. Also trying to get poly bushings for the 34mm bar is tough. Go with the 30mm and poly bushings. Quote Link to comment Share on other sites More sharing options...
