....with a stock set up? Is it the bolt holes or the pocket the strut block sits in?

Is there any negative camber to be gained by elongating the bolt holes?

Not much to be gained but lowering your suspension does.

Amber Gramps

Lowering is part of my problem. I've got stock 16x6 Fuchs wheels, stock sized R compound tires over 930 calipers and a 3mm spacer with an arch height of something like 24-1/2 inches. It's tight, really tight. Already shredded one tire catching a lip at an autocross. I just want a few more millimeters without having to invest in adjustable camber blocks. Using the de-cambering lower ball-joint will add negative camber via the bottom of the strut, but it also widens the track, totally the opposite of what I'm trying to do.

Have you asked Chuck Moreland? I used his offset ball joints, in conjunction with his monoball camber plates on my 84 track car, running 225s on 16x7s in the front, with no problem. I did roll the fenders though.

It should be the hole stamped in the sheet metal as the limitation. The "lip" in the stamping looks to provide strength, I'd be leery about enlarging the hole, but that's just my opinion.

Aftermarket upper plates have a smaller diameter bearing than the rubber donut and get you a small amount more adjustability, but not a lot:


Rolling fenders is another option.

Between rolling the fenders, upper camber plates, pulling the strut dust covers, and monkeying with wheel offset, I was able to fit 245s on 9" wheels under my narrow body Carrera front flares.

Oh, and at SEMA this year KW showed a super trick camber plate better than any OTS option I've seen:



It sets the whole spherical bearing below the sheet metal hole, so you'd only be limited by the tiny adjustment ****. Badass, but I can't find them for sale separate anywhere, nor do I know if they'd work with anything other than their own coilover strut.

Chuck's solution would be the ultimate option:

Man that's ****.

Too rich for my blood right now for a lowly street car. You guys are trying to get me to get out of my chair and actually go and look at the car myself. LOL.

Looks like ERP has a couple options but no pricing. Looks like Steve is a distributor

The Elephant quick change ones don't give you any more than the Tarretts though, as you're still limited by the hole in the sheet metal.

I have the cheapo eBay "Deutsche Parts" ones. The cool thing is they have an extra set of bolt holes so you don't run out of room. The bad thing is the spherical bearings started dying almost immediately. Total junk bearings. I replaced them with some higher quality ones and they're fine since.

Amber Gramps

^^Saw that option and saw the crappy reviews on the bearing and decided to stay away.

Gotta find the Tarrett ones. Love Tarrett

Jaime to the rescue with his picture below. Looks like there is some wiggle room there.

Holy Crap that would be cool. Kill two birds with one stone.

......or I could just change the angle of the axle on the strut.

Doug, get a used pair of struts that you can modify the spindle on. Raise spindle, increase neg camber, and revised dampening all in one. Also gusset the spindle for track work.

You can choose to either keep rubber strut mounts or spherical ball mounts. The point is that you are probably only going for a degree or so negative camber, and still want to drive on public roads I assume.

Good news - I had this done on my car and got -2.6 degrees negative camber. Excellent for auto-cross.

Bad news - These are not adjustable (other than the small adjustment at the top of the strut mount). Not so excellent for street use. Unless you confine most of your driving to the canyons, you get wear pretty quickly om the inside corner of the tire.

Amber Gramps

No plans to do anything but street with the car. Just looking for .5° or so. Just moving the top of the wheel inward by 5mm would do the trick. Unfortunately I only have about 1mm between the wheel and the 930 caliper so I can't just use a thinner spacer.

You could install some of ER's decambered balljoints ... i have them on my 89 as well as their adjustable camber plates, i could get way more camber than i need !
I DE'd my car pretty aggressively for 6 or 7 years with the balljoints and they're still as tight as new !

^^^ I'm not trying to get more negative camber for the sake of getting more negative camber, but to create more clearance between the tire and the rim lip. It's a distance issue, not a performance issue.....but ya, that would be my first step if that were my goal.
