What do you think about this setup?

well, on one of my Iroc's,
im getting ready to put in some new floor pans. anyway since everything's off the underside im thinking of doing the stuff i listed below

Sub frames

Struts/Shocks - i was thinking KYB but but should i just get stock?

1.75" dropzone springs, we put these in my friends car and it got really stiff! not sure if that's a good thing...

tubular panhard bar,
box the LCAs or i'll make tubular ones useing 1" tubeing,
LCA relocation brackets?
tubular torque arm,
my iroc also came stock with the wonder bar, but should i add a thicker bar? it seems kinda flimsy,

front and rear strut tower braces

what should i do about the bushings?

a few things, i would double check ,your ride height. im on sportlines and its really low. but i think that using 17's ZR1's are closing that gap a little more, so check your exhaust and make sure its tucked up as high as you can go

how is your budget for shocks? are you going to be drag or just aggressively street driving? i have KYB GR2's because they were a good price and better than stock. if i had more money i think i would buy some Tokico's. but if this is an everyday car, KYB's will do the job, just dont expect them to be super duper racing shocks.

about the panhard bar.. if you are lowering, get the adjustable.. you'll need to recenter the rear and the APB is what you need.

LCA brackets.. get BMR bolt ins.. nothing else.. super easy to install, superior design to everyone else.

i dont think you'll need a torque arm.. but, if you want it, go for it.

dont bother making tubular LCA's.. there are too many companies now that make them in really good quality and very cheap.. i got mine from UMI performance, powder coated black, shipped for 80$.

i also got my adjustable panhard bar from Ebay, a guy makes them, super awesome quality, 75$..

my last recommedation is once you have all this done, get an alignment.. i have everything you listed, and set my Camber to -.5

hope this helps.

if i had better shocks it would be perfect.. it corners like a madman, but the ride is a bit rough.. lowering brings to life all the rattles and sounds you never heard before..

im using 17x9.5 ZR1's with a 4th gen rear.. tires up front are Goodyear F1's 275/40 rear's are Sumitomo's HTR ZII's 275/40

i really like these Sumitomo's great grip, especially with all this rain we have had.


i also need to install my Strut Tower brace.. i bought the Hotchkis version in black, still have yet to make the intall.

the bushings are still stock rubber.. one day i will change them out for better ones.

pic of the rears.. kinda reminds me of the Goodyear GSC3's or whatever they are called.

price i paid was 140$ each tire.
