When your suspension turns into a tyre lathe

[TurbostyleR]

Glenno I know what you're saying, however when I was driving the load was minimum. I was doing the speed limit and wasn't turning suddenly or anything like that, and the car isn't fully sik low either.

I'll probably take the strut out next Sunday and see what's up. If fulcrum aren't going to anally ream me for the price of a rebuild (if possible at all) then I'll just get the front pair rebuilt and get on with my life.

Was on the stops as it was. I was pretty fucking hectic back in the olden days.

saw a VP in a bunnings car park go over a speed hump and the drivers front wheel pointing sideways. Made sure the lady was OK and asked her if if her son had lowered the car, got yes how do you know my son, explained to her what happened and why. Would have liked to be a fly on the wall, as it was 5 years old at the time

... and thats why the cops are so tight when it comes to anything thats modified....


and i yes, i been young once and did sim8ilar stuff that when u think back now was really dangerous.
(i had a torana+308... very very unroadworthy lol)


edit: adding to that i am in no way suggesting your car is unroadworthy or that you do not know what you are doing.

It actually looks like inner edge wear from a very poor alignment to me, if it was an adjustable spring perch that did this I would expect to see different markings on the tyre. plus if it was touching bad enough to wear to the belts you would know as soon as you drive out the driveway as you would feel a massive pull.

It might have cut through after the tyre let go. The fact there aren't shards of hot sticky rubber around practically everything would mean it's probably not really rubbing away. That much friction, the rubber grinds off red hot and usually sticks to whatever it touches. Have to get in there with a scrubbing brush and goo remover or a heat gun to get it off.

@ dyno.

I thought the same.

Tyre looks funny on the shoulder of that removed wheel; poor alignment is a plausible reason. The absence of photographed exculpatory evidence in the form of a damaged strut makes it more likely.

There is no way it would wear that far down the side, that has either been rubbing something or run flat, what I fail to understand is how did he not hear that, I have had the tyre rubbing both the strut and body and both made horrid sounds.

Looks more like rubbing on the inner guard.

Done the same once, looked identical. Just a very slight rub when the bushes are compressed, tyre is contorted a little and car is near full travel that I couldnt see in static conditions in the normal ROM without the shock in place.

Ive seen tyres come in with no lettering on the sidewall anymore it's worn that far over. You would be surprised what you see.

I used to get a similar pattern on the rear with only 2.5 degrees camber. If I have left this wear away probably would have ended up the same.

[Glenno]

WTF are you doing running that much camber on the rear?

[myliberty]

I'm going to go ahead and assume you had 7" wide tyres stretched on 8" rims for fully sick flat brim stance along with 4 degrees of neg camber and some toe out.


That's what you get.

Your coil overs are fine, your life choices? Well that's a different matter.

[TurbostyleR]

I didn't even notice the wear on the inside to be honest! Just looking at the photos again after the comments makes it look like there is heaps of inner edge wear.

The front suspension has fuck all negative camber so camber is not the issue. When I put a stock S15 rim on it to drive it home it fouled on the coilover exactly where the rubber was taken out of the other wheel. To drive it home I had to use a 5mm slip on spacer and the S15 wheel.

I also did drive the wheel flat for a good 400m or so at under 20km an hour as I had no where to pull over on that patch of the road.

Like i said in the initial post, I heard a funny sound after driving the car for a bit, it was loud enough for me to pull over and inspect what the issue was.

[Rdyno]

If you are stating that the front needs more camber which you would think is right due to castor and the rest you may be mistaken. Some cars actually run less camber at the front for reasons unknown to me i'm guessing bush compliance and sai. I wheel aligned a porsche cayman the other day owner was complaining of tyre wear and over inflation dicks at the tyre shop set the psi to 40 all round on the new set. Anyway adjusted the pressure to what porsche recommends got the recommended settings up (which I rarely do) they were pretty much what I would run except the front cambers which were low.

Front camber 20mins each side toe 1mm overall in

Rear 1.3 degrees neg of course and 2mm overall in toe

I would of run the fronts at like 1 deg with .5-1mm toe out but hey i'm just a technician.

edit this is just one case I noticed recently on a sports car using low cambers.
