I'm fitting adjustable camber arms all round to get rid of my tyre wear problems.

 

What do you recommend I set things to considering I've got 18x10" wheels with 285 tyres, wide arch kit, Blitz lowered springs, Koni adjustable shocks and whiteline anti-roll bars.

Should I just get it adjusted to the stock values or are they a bit conservative for my uprated beast?

 

Oh, and what are the stock values?! :D

Try setting the front up parallel with about 1.5-2.0 deg -ve camber, 9-10 degrees castor.

Rear: 1-1.5deg -ve camber 3mm toe-in.

 

Worked well on mine. Took that initial dartiness out of the front and steering loads up nicely with 9deg castor.

Should the the rears not be set up with zero negative camber - mabe even a touch positive to allow for the fact that the car is set up unloaded? with this big tyre width you want the wheel ultra square to the road when its loaded up. Any hard acceleration makes the rear squat a bit and with that comes negative camber anyway due to the geometry. You also get toe in as well. So I would think you want the rears also with zero toe in. Big power tends to pull the rear suspension out of shape enough to make it toe in under acceleration anyway.

 

Thinking to wear patterns I'd go with what John says on the fronts - mine always wear slightly more to the outsides than insides suggesting more neg camber would be better. However rears are the opposite on wear suggesting to me anyway that less negative camber would be better. Mine is stock UK with new UK actuator rear shocks and its hard enough and with no spring sag and normal ride height but the stock top links are already maxed out on camber and its still slightly negative.

Car isn't set up unloaded, measurements should always be made with car fully on suspension. A little bit of toe in seems to help the rear come round a bit during cornering.

The wear has little to do with camber unless it's miles out and more to do with toe in/out scrubbing the edges as the tyre is effectively dragged sideways when going straight.

What I'meaning by loaded is with bodies on seats and a full tank, not just sat on its wheels empty car.

 

I know what you mean by the toe in issue. Mine had 8mm rear toe in when I got it but it still scrubbed out the inside edges first due to the neg camber and this was on 265s. You would normally expect excessive toe in to scrub the outer edges! This is true on skinny tyres but not on wides with some neg camber.

 

Previous owner had just had rear HICAS arms done and hadnt bothered to re track it on mine.

 

Needless to say it handled funny in the wet and disappeared the rears in less than 3K.

 

Mine is on 0 toe in rear now and handles well and wears much much better.

mate take the car to a "propper" suspention company and have them set the car up. I went to LEDA in chelmsford. top people, top company.

That's interesting because I'm about to have my HICAS arms etc replaced this weekend as the arse end is squirming all over the place and my rear tyres have suddenly got massive inside wear.

Is this common when the HICAS wears out?

Was thinking it's more the camber being out but maybe not.

How much are we looking at for that?

Will I have everything they need to fully adjust things?

I had my 97 na suspension geometry sorted by a local accident damage repair company after I replaced the lowered suspension with standard suspension. That was 6 months ago andtyre wears great drives straight too. Cost £64.

Im having mine done next week at RSE Motorsport where they have just installed a laser alignment system(not cheap) and are doing a introductory offer of £75.00.

I have asked about a club day and they are up for it,allthough they cant come down on their price as its allready rock bottom.

However they did say if we want they can do a BBQ on the day.

All so it would be a good chance for you all to see theyr 1000bhp supra,600bhp Skyline(just arived) and theyr track NSX.

LOL! we charge £158+vat to setup & adjust on our Mercs :x: thats a bargain!!

It certainly was !! :smash: :D

I know Paul they said the system cost them K24 and they cant keep the price that low for long.Oh thats £75+vat still cheap.

It certainly was !! :smash: :D

I lowered an Omega MV6 (no laughs please) and had my local accident repair garage set it up, and it went round the bends like you wouldn't believe and no tyre wear at all. £49 for the pleasure.

wasnt much. as for have they got everything, err. they make suspention. the are LEEDA. last time I went in there they where working on 2 GT Jags and a complete chasis for a rally car.

 

give them a bell they are in teh book. if you do a search youl see I posted about tehm about a year ago

I was asking if I'd have everything needed on my car ;) lol

As in will I have a fully adjustable suspension setup with the adjustable camber arms or are there other bits available to setup a Z's suspension properly.

Just look on the SPL website then phone smithy and buy one of everything!
