ive just recently got mine on the road and to be honest i think the handling is garbage.... but i'm sure it probly just mine. it tends to understeer or oversteer but its unpredictable which way its gonna go.... the car is lowered and has koni shocks the rears are on the hardest setting but how do i check the front are on the hardest setting? which bit do i turn? there seem to much body roll.

what suspention set up is well recommened?

cheers

 

Have you hand the alignment checked since you lowered it ?? Don't forget you've pulled all the suspension apart, chances are it needs re aligning. What suspension kit did you put on the car ? Koni's + what springs ?

Doesn't it say on the adjuster knob which way to adjust the stiffness of the shock ?

Crap tires will cause poor steering response etc but I'd imagine its the same wheels/tires that you had on the car before you changed the suspension.

Also having the shocks on full hard is not ideal, body roll is controlled by the springs & AR not by the shocks. They just control the springs compression & rebound rate.

 

the whole suspension was already on the car when i got it, ive only just started using it properly i think i will get it up on a ramp and check it first i'll going to try adjusting the front shocks hard to see if that makes much difference
.

cheers

 

It may be worth fitting "Cosworth rear suspension shims", small simple, but they seem to make a difference on my car (Konis & lowered).

Speak to MikeR about them.

Also I tried mine set on full hard, fine for track (smooth road) but too responsive and unpredicable, IMHO, soften mine a bit at the rear, and bit more at the front.
+ shims, mine now handles really well IMO.

Did this sort out the rear tyre wear ? My suspension is out of alignment after fitting the same kit you have. Just looking at my options.
Cheers.

 

I would say there is more even wear, but I havnt done the millage to really tell.

But it did take me a little time to get used to the way it handled with the shims.
Now I am used to it, I think it understeers less, and you can push it harder rounder the bends, and instead of it understeering it just corners!
I have not pushed so hard as to find the limit, I suspect it will eventually understeer, then possibly oversteer.

Engine is sick, so havnt driven it in a while, new engine, 2009? maybe.

hard/stiff suspension is not always good!

 

Cheers Gav, worth looking at the shims then.

 

Hi!
How much did you lower your car? I also have koni and lowering springs, mine is 25mm lower, and I want to use shims for better traction.
How thick was your shims? I can choose between 1mm 1,5mm and 2mm. They are thicker in one end and thinner in the other end.

Koni Shocks, Ahmed Springs, I think it lowered around that amount, I will have to check.
Shim were thin, thinner tham 1mm im sure. 2mm would really mess the handling up, unless you know what your doing.
Buy Mike's kit, tried & tested, with instructions.

If funds allow, buy an adjustable rear beam, and have it setup by a pro.

Mike knows more than I, he might see & reply to this post?
Gav

 

Yes, nice if you could reply on this one Mike.
I am considering a Koni/Ahmed combo but will i need the shims on this combo?
I have also heard about bolts breaking on the bearingcarrier when using shims.
Anyways i will call you when i get to that point where i need the suspension parts.

 

Heard a lot of good things about using shims but wasn't aware of different sizes.
What exactly is involved with fitting them?

 

I would stick with Mikes kit, right thickness for the job & comes with instructions on how to fit.

Gav

 

I'm interested to know what needs to come off to fit the shims?

 

From memory, take the wheels off, calipers & discs, then loosen hub bolts & slide the shims in. Rough guide.

Im sure others on here must have tried/using them I wonder how they are getting on? improvment or not?

Best solution is to buy an adjustable rear beam, and have the whole car setup correctly.

Gav

 

Gav has pretty much answered all the questions.

My shims are NOT like the camber wedges that are sold (which IMO will stress the hub, so I won't sell), mine only improve the toe, NOT the camber.

If you want any more car specific info, just send me a PM .
