What Next? (If Anything)

Ok guys i think my suspension is where i want it. Just seeing if you have anything else you think would be beneficial to a street driven car.

KYB GR-2s (not the best i know)
Stock IROC Springs (might get a lowering set)
36/24MM with poly
wonderbar
STB
SFCs
J&M poly ball LCAs
UMI adj. PHB
245/45/17 w/iroc reps (need to order yet lol)
EDIT: forgot my LCARBS

What would you add?

Re: What Next? (If Anything)

I see you have a STB but you didn't say if you have replaced the upper strut mounts. So that's something to think about. A solid bearing mount from Spohn or J&M!! Also, how long since the steering linkages been on the car? It may help if you replace them, don't forget ball joints.

I also suggest the UMI double adjustable PHB. It's only $20 more than the single adjustable one. And the ease and simplicity of use is worth it.

Re: What Next? (If Anything)

Car has <70,000 miles on it and i've checked over the steering, shes nice and tight yet! I think the J&M strut mounts are only $217 shipped, not to bad considering what i've spent on this car already lol. I'm kinda planning a front brake and suspension upgrade in a year or two (wilwoods and "maybe" a K-member?) so i might do the mounts then.

Quick Question, how much would you pay for a 3.42:1 89 iroc posi rear axle with like new PBRs? I could get one for 300 bucks

I'f the limited slip is functional, I'd go for it.

Re: What Next? (If Anything)

I agree with what's been said- new strut mounts. I personally prefer the J&M pieces.
What tires are you going with?

That's what I paid for a 95 or so rear with disks/posi. Does the rear you're getting have the older style rear brakes?

This whole rim package http://cgi.ebay.com/ebaymotors/17-17...Q5fAccessories
Again not the best, but they got to be better than what i got currently (BF Goodrich Radial TA 245/60/15).

I might have to wait on the mounts and diff., i got to finish the apparence side of my car first (3500 in paint, another 300 in weatherstrip, 300 in decals and emblems, 1200 in rims/tires) since its at the body shop anyways i might at well make it look awesome. I can always do mechanicals, but body work and putting the stripes on straight is not my cup o joe.

Re: What Next? (If Anything)

Yea, those would be a little better than what you have now, judging from the ratings on them. I've not heard of those tires in particular, but they seem to be pretty good. My next set are going to run me about $125 per tire. Going with the Sumitomo HTR Z IIIs in 275/40R17s.
I know where you're coming from on body work. I've been tabbing up what my next mods of exterior mods are going to run me (shaved antenna, smooth S10 handles, shaved badging-bumper, ground effects, nose, taking the fenders, bumpers, door molding, ground effects, etc off, all new weather-strippin and repainting the whole thing while apart) and it's looking scary. But that'll be after I do the LS1/T56 swap and I graduate college.
