is there an aftermarket setup(springs, shocks, bushings, etc.) that will make my 1991 1LE perform the same(or better), but have a little smoother ride?

Unfortunately "performance" and "smooth ride" are usually mutually exclusive terms.

 

That's the whole reason the 1LE wasn't offered to the public as an option....b/c of the racecar like ride! Add polyurethane engine & trans mounts for an even harsher ride, I did, but it's so worth it performance wise!

------------------
'91 Z28 1LE; 355, Sportsman II heads, Edelbrock TPI w/ 58mm TB, Tremec TKO 5-speed, 3.73's & much, much more

 

When you find those magical springs let me know. I'll take yours.

Some are faster but mine's fast enough.

 

what is all different from the 1LE and my iroc? i mean suspension wise, i already know about the fuel tank, drive shaft, and brakes. i am assuming they have different springs and roll bars?

 

No, the springs and swaybars are a misconception. In '92, there were only three front swaybars offered. Either the FE1, FE2, or F41. There is no "1LE" bar like everybody thinks. FE1 was the "soft ride" wich got the 30mm sway bar. The F41, which was the "firm ride and handling" had the 34mm, and the FE2, which wasn't just for the 1LE "package", it also could be had with the WS6 or Z28, as it was the 36mm.

As for the springs, there were about 4 different versions, none are 1LE specific.

What is the difference with the fuel tank??

------------------
'86 TA, T-tops, T-5, 3.73, 4 wheel disks 350, compucam 2040, performer intake,SLP Headers, 3" race magnum muffler, 1.6 Comp rockers, Ripper shifter, perf. friction pads, Hypertech ignition, Earls brake hoses, Hotchkis springs, Tokico Illumina 5 adjustable shocks and struts, Lakewood panhard and trailing arms
14.73 @ 95... traction still a problem

 

thanks for the info GMtech. slowTA, the 1LE (and i believe b4c) fuel tanks are baffled to reduce sloshing during hard cornering.
