C34 Wheels/suspension Help Plzzz

[SNEEZYC34]

Hey Guys,

I have a c34 stagea, auto, rs4.

Now i have always had decent wheels and the stagea is the first car i have ever had that i have used wheel spacers.

I am running 25mm bolt ons all round.

I have fair crappy tyres also that came on the car, chinese kingruns (new tyres are coming with in 2 weeks)

One thing i ahve noticed since i have put the spacers on, is if i am driving on an un even surface or the road is not flat it seems to pull around a bit when it hits an uneven part of the road.

Is this common? i ahve search on the net but cant seem to get 100% straight answers, like i said this is the first time i have used bolt ons so i have no idea how they should feel.

I dont really want to take the spacers off and the wheels dont have the best off set and look terrible on the car./

any help, suggestions would be great

Thanks guys

had the same problem when i went from cheap tyres to expensive tyres - turned out the expensive tyres were too "square and stiff (runflats)" for the hard suspension on my car and they would fight each other to sit the car flat on the road. Guy who sold them to me said the car was the problem... later i put on some cheapies with softer sidewall and more rounded edge and the problem was fixed. I am also running 25mm spacers but only up front.

Using wheel spacers changes the Scrub radius, this does changes how the car steers...

Is running spacers really worth it on the road.?

With the whole defect and possibly insurance issues it brings why not get correct size wheels?

prob not but im gonna leave them on, cant really afford decent wheels at the moment as house stuff is more important than car stuff..

will have new wheels once i save up some money, but y the loks of it a lot of people run them from my research.

[SNEEZYC34]

I also have some slip on spacers at home, could try them instead and see how that goes as well maybe

[Ben C34]

For sure alot do run them,and don't get me wrong I'm not driving an undefectable car!

It's just that you can do without them if the wheels fit correctly.

process of elimination from cheapest/easiest up - firstly what did you change to make it happen. Try other wheels, if its still there its not your wheels, (if it isnt, it might be your tyres) - then try without spacers (if the wheels fit) - then try other tyres... pain in the bum, i know, ive been there, but there is nothing worse than a poorly handling car, especially if it was ok before.

[SNEEZYC34]

Yeah well i also have 7mm slip ons and 15 mm slip ons at home, dont think i will have enough thread for the 15mm but could try the 7s

[SNEEZYC34]

Yeha well the rear seems fine, and i have only recently put them on the rear..... its just the front that seems to pull and its had 25 mm bolt ons since i brought the car ( i have treid to take them off, with a heat gun etc and they aint moving) everything under the car is good, i have all new sway bars, sway bar links etc. hence why i am thinking tyres, one thing though is i was told to run 40psi in my tyres, but then tyre power at smithfield said to try 32 psi?

[bentwagon]

tyre pressure would be the cheapest and easiest thing to try

to point out the obvious have you had an allignment done? you may have odd toe or caster creating an isssue which crappy tires are magnifying.

[kjb_r33]

Seriously? If your not interested in the correct answer, based on steering geometry, why ask?

[SNEEZYC34]

32psi seems fair low aye

the f**k u on about?

[SNEEZYC34]

im asking all the questions u twat

scrub radius - it was the excuse I got for the tyres - yes it may still happen on a dodgey road but not the 1/2 foot jolt to either side for a slight indifference in the road surface. Like i said - best start with the cheap fixes first, and as far as my bolt-on spacers go - they were put on to see if they would fix the problem I had after putting on the tyres that didnt suit the suspension of my car.

[SNEEZYC34]

Well. As I said I have always had 25mm Bolt ons from when I got the car. I have taken the rear 25 mm Bol ons off so will see how that goes. Have also lowered psi to 32 as suggested by tyre power. See how that goes cheers for all the suggestions guys

I doubt its the spacers as I have 25mm rear and 27mm front bolt ons (and my car is legal/certed).

The reason I have spacers is that my Ce28Ns cost $1800 a set.. To get the right offset I would have to order them from Japan at about $4000 so spacers are the answer for me.

As for steering geometry the effect of spacers is exactly the same as getting the "right" offset with no spacers.

Cheap Chinese tyres will definitely not help. I never skimp on tyres. I am currently trying some new Nitto Invos and they seem fine so far.

[SNEEZYC34]

Yeah exactly you have a pic of yours?? The wheels I want with the right offset are $4200 which for wheels is way too much

Sorry its dark now. The pic below won't help much as its side on with my trial wheels which are the same size and offset as my new ones. I'll try to take a pic tomorrow to show the fit of my Rays.

Just found a couple of end on views - these are my last set of wheels but the fitment is exactly the same as my new ones:
