IROCDave

My wifes 90 IROC drove fine with the stock 16" rims and 245/50/16 tires, no slop, didnt pull and no vibration / shimmying felt in the steering feel. When I put the 17" rims and new Michelin tires on it the steering felt looser and I could feel a slight wobble in the steering wheel. I would like to rebuild the front steering system. I have used a PST rebuild kit and will never buy another part from them again.

Anyone had good luck with a complete rebuild kit?

I used a PST kit on my 87 and broke one of the tie rod ends while installing it. I picked up another up from NAPA and was suprised how much beefier the NAPA (DANA) parts was. I am wondering if anyone has seen a kit with quality parts?

I havent seen any kits with better parts. I used the pst kit as well. But working at napa the napa chassis line is definatly better. The mrc line is about equivalent.. or maybe even slghtly better then the pst. There's not that many parts, you may just want to piece it out.

I used the PST kit a few years ago as well. Did the whole thing from polygraphite control arm bushings to TREs. My control arm bushings are cracked and broken now and TREs still have pretty good stiffness. However, comparing them to the moog ones I sell at work they're tiny. I'll be piecing together mood parts soon.

I just received my del-a-lum control arm bushings and moog balljoints so I'll be swapping those out in the next week or so. Very Happy

Ian, if you haven't put the ball joints in...check out the precision ball-joints that Coleman Racing sells. IIRC they do have the correct ones for our cars, and you can get them at 0.5" longer than stock, to help push the A-arm down, since your car is lowered so far. They are the joints I am doing next time I have the spindles off my car.

Damn you John.

Their site is a little cumbersome to navigate. Are you talking about the ones marked 'Howe' ? I see the style ours use (k6145, same number moog chooses). What indicates taller?

EDIT; Perusing TGO I searched "extended balljoint" and got an old thread you talked over the subject with Dean. Seems like a win-win situation. He mentions Coleman pt# 835-450 (This.) Is this the one you're talking about? Duuurrr. Nevermind, that's a rebuildable monoball not really suited for street/DD apps I guess.

It should be a Howe racing number. IIRC we use 6145 style on our cars, so any flavor of the 6145 style should fit.

So monoballs you can adjust the height of the stud to get the .5" drop? (hypothesized from this post.) I guess I should also be looking at bumpsteer if I really start messing with spindle heights and such.

You can change the stud for a longer stud, or buy them with a longer than stock stud.

It will have a negative effect on bump steer, so you would want to probably run a bump steer kit. What it does it help raise the roll-center of the front suspension back up, and also gives you a slightly better camber curve.

It's a catch-22 really, it helps one thing, but then you have correct another. pretty typical, eh. Luckily Baer makes a bump-steer kit for our cars, easy deal. The hard part is measuring the bump steer.

All of this is assuming you have the G-C weight-jack kit (I thought you did, but I forget). If you don't, when you put the longer stud in, it will lower the front of your car further.

Well, unfortunately I don't have weightjacks so I won't be able to correct the ride height change and the monoballs along with bumpsteer kit probably puts it out of my budget for right now. I'll toss the delalums in with new moog balljoints and order the monoballs for later when I scrounge together some money for the rest of it. Oh well.

Did you use the full GC kit with the tapered rear springs or did you use the GC front and stockcarparts rear for standard sizing? Maybe I'm remembering that fuzzy but I thought the GC setup used an oddball rear spring to fit our perch?

I am wanting to go to the del-a-lums in the camaro.

I wish they made others, like for chevy trucks. Thats one of the first things to go on them *sigh*

i used the whole G-C setup, because I got a great deal on it used, but not installed from someone on TGO years ago.

I like the 5" stock car parts rear pearch, if I was buying new rear springs, I would go that route.
