4 wheel alignment within tolerance

[warpc0il]

It's not just a case of "Standard" or "Sports" setup for the alignment.

All our cars came with Sports suspension, so using the "Sport Suspension" table is correct, while the "Standard Suspension" table is wrong, for our cars.

Though you can see why many owners and most dealers/garages get confused, thinking that the car is "standard" i.e. "not modified"

ive just found the details of the set up on my pz from its last check in 2014,i have 2 pages,im assuming before and after?...whats the collective opinion on these?it was std at the time.
i have fitted 15mm spacers and racing beat arbs since and the new pz suspension will be fitted soon i hope,does it need resetting? i use std tyres(contis) for road and 235 40 federal 595s for track.
i drive it fairly hard from time to time and a few track sessions have been done and a few more planned.

To be honest I can't really make heads nor tails from those printouts.

+8 rear toe in on one side surely cannot be right?

[xamtex]

i cant make sense of it either...not that i have much sense anyway...hence the request for more sensible people to try and make sense of it!

[xamtex]

it has had the n/s rear repainted...remember the dodgy paint...could be its had a bump at some point?

[kopite72]

I can only speak for myself here but after getting the alignment done with the sports table set up the car was much much better and I'd recommended it to anyone.

I said it in an earlier post but don't underestimate wheel balancing either. The effect of a perfectly balanced set of wheels has on a cars handling is big. My cars handling has never been better since having the proper alignment table applied to the car along with wheel balancing...

[xamtex]

all my tyres..9 of them have all been balanced and i have no sign of wheel imbalance,in fact the car seems to handle well,but as its my first rx8 i have nothing to really compare it to...maybe i need nick or someone to give it a run and give me an educated(i use the term loosley)opinion?

[13Black]

You'd know about 8 degrees on one wheel. The tyre wouldn't last the end of the forecourt!

Also the other image of it being 2 degrees overall is totally massively too much still. Impossibly high surely. It's meant to be about a quarter of a degree overall.

I'd say ignore the files you have and get it checked again.

[xamtex]

i will wait till the pz setup arrives,it handles too well to be massivley out and i have no unusual tyre wear.
any reccomendation in the midlands for checking?

[xamtex]

just found a place in nuneaton does a free check with a £100 price cap if everything needs adjusting...its a hunter machine they use...how does that sound?

[13Black]

Sounds about right to me

Spacers won't make a difference. Neither will ARBs. Nit picking, they may warrant you to change the alignment slightly if you know what you're doing and are chasing tenths. But none of us are so it's fine

New PZ setup may raise the car slightly but it'll be neither here nor there. But if you're gonna do it, might as well get it done a few weeks after the new shocks are on and settled.

[xamtex]

my thoughts exactly nick,i will wait till i get the new stuff on.

[PeteH]

The cambers are in degrees, and the toes are in millimetres. That's why the results look unusual. The only thing bad about your setup is the amount of "crabbing". By this I mean that the rear toes are setup asymmetrically, so the car is permanently "steering" from the rear. This can create pull when trying to drive in a straight line. It can also mean that your steering wheel won't be straight (is your wheel straight?).

The second sheet is nothing to do with your car. It's just the basic settings for an RX-8.

And I think they used the sport settings, looking at that sheet.

[xamtex]

says sport on the sheet,drives straight,take hands off wheel and it does not stray at all.

Hi, would you please give their name or web address, assuming they appear to be good, please?
Even better for me will be somewhere in South Wales preferably near Cardiff. Any suggestions, anyone?

https://www.facebook.com/thetyrecompany.co.uk/ not had mine done yet,still waiting for the new suspension to arrive.

this is a useful search for alignment.

I have an issue with my alignment also it would appear
The tyres were changed last year for RainSport 3
I recently noticed my front nearside tyre had worn down to the banding on the outer edge, offside front perfectly flat even wear. Then found both the rears had worn down in the same fashion but on the inside edge.

So off to see the hero’s at my local Kwik-fit to have it all checked. They use the Hunter system as well.

As you can see from the before and after readings, to me anyway, they only had to adjust the front nearside.

I have a just bought another set of RainSports to be fitted, but am reluctant to have them fitted as yet until I have the issue sorted.

At the moment I have my spare set of Sessanta’s on, but as you can see the tyre is not sitting flat and you can see it is leaning on the inner edge?

I have Bilstein B12 pro suspension fitted, which is around 2 years old.

Any suggestions as to what could be wrong would be greatly appreciated

Thanks Graham, I actually got his number off Chris Holmes on Thursday night, I will give him a call. I was just posting up in the meantime for information purposes and just to put it out there, so to speak

I have a friend close to caerphilly who has a new machine and is very reliable

The problem with somewhere like Kwik fit is that they don't do your geometry, they only do your toe....

Your rear camber is way off. It's even higher than my track car, and far too high for road use.

Your front is fine. My guess is that your tyre pressures are far too low. And you may have been pushing the Rainsports too hard during the hot summer months. The front left outside shoulder is always the one to go first, because that's the one that gets the abuse around roundabouts.

It's also worth checking your front suspension bushes. If they are worn then they will contribute to this wear pattern.

And finally, I wonder if the Bilsteins make the car understeer more. That would also create this problem.

[PeteH]

Oh, and do you run spacers? Any chance you have got rubbing? Your wear pattern is so odd that it looks more like rubbing than wear from the road.....

[13Black]

20mm apparently. But that's a fairly standard offset, so surprising if it's hitting the metal wing at that :O

[Dave2112]

Yeah 20mm spacers, I forgot to mention I have done 4 track days on them as well. So yes you may well be right about the nearside front wear, as the majority of bends are right handlers. Not noticed any noise or feel anything from rubbing tho.

Would fitting white line or Racing beat anti roll bars make much of a difference?

I am going to go and see Fergus Walkinshaw As has been suggested, so hopefully he can sort it for me.

Thanks for all the replies

[ChrisHolmes]

Thruxton probably killed them finally!
