Shock absorbers?

My 2006 WRX PPP is just out of warranty, so having a little tuning work done .

Had Eibach springs fitted to lower the car and handling is definitely improved. However, I immediately noticed knocking from the rear suspension. VERY noticeable at slow speed over uneven tarmac (as we have round here in deepest Cornwall to put it mildly), or under heavy braking. However, not noticeable at all on good tarmac at speed.

The car has gone back for the rest of the work to be done and for the suspension to be checked out. Nothing obvious has come up. The springs are seated fine, etc. However, we've found that the rear wheel bearing is duff and I'm going to have to replace it as well.

The only thing is, I can't see how that will be causing the knocking. Sounds like dampers to me and the threads here suggest it's a common problem on the new age cars. Any thoughts anyone?

If it is dampers, I'll go aftermarket if the OEM ones are rubbish. Any advice on best for fast road, non-track day use, at a reasonable price?

Cheers.

Re: Shock absorbers?

Sounds like the struts knocking as you say. Even if you get them fixed it can(i believe) come back.
I have AST coilovers on my car, and i recommend them. They are fully damper adjustable and can be adjusted from the top of the struts inside the car(knobs on back seats) and from under the bonnet. There are 12 settings going from softer than normal STI to hard and bouncy(but never too hard). I often change the damper settings depending on how and where i'm driving. They are good for british roads, unlike Tein coilovers which are very hard.
A place called Powerstation in Gloucester sell them and fit them. Remember to make sure you have a full 4 wheel geometry alignment done when fitting new suspension. You can get a whole suspension package fiitted by the above companyif you are willing to payfor it, for example,
Stage 3 - T25 Spec Kit
AST Sport-Line Suspension Kit
Rear Adjustable Roll Bar
Anti-Lift Kit
Front Adjustable Roll Bar
4-Wheel Alignment
1450* + VAT



The AST coilovers alone are about 800/900 + whatever for fitting + about 70/80 for the wheel alignment


By the way, I'm not on commission from them , but have that exact package plus front n rear strut braces and it's fantastic.

Re: Shock absorbers?

a decent set of kyb shocks and eibach lowering springs will be half the price and do just the job.

coilovers on a road car are pointless, they never get adjusted and are just something for pub talk unless your racing and adjusting setups to suit each track etc

Cheers.

I've already got the springs on and the Kybs look like good value.

Front and rear or just rear? Thanks.

i adjust my dampers all the time, it's fun to change the ride feel and i don't go down the pub n talk about it. I come on here and talk to you about it.

but as you say, he already has eibach springs so kyb shocks would be cheaper,, - but not as good/rigid/flat n tight as my set-up

Having driven Brumbrum's Spec c around the track... several times

I can confirm when it comes to Scoobies...he is not a bullshiter who talks bollocks all day long about horse power and rolling road figures and who has the biggest end pipe, down the pub or on any blog site

He does however talk bollocks about everything else

The handling set up on this car is fantastic... it makes a big diffence to everyday handling and track handling... it's really smooth for such a sporty package and allows choices and options, and that's the key to satisfaction IMHO

It is easy, very easy infact, to adjust

I was amazed at how the understeer that fecks the handling of the Impreza is gone... it is dialled out.... with the right tyres the car is amazing (R888 Toyo's) and for the track the semi slicks

I have, like many on this site, tracked all of my cars at various places, and I have driven many different models around Coombe and at Prodrives testing ground... The Impreza is a brilliant but flawed car, some work is required to refine and bring out the well hard diamond from the washed out front end boat steering Standard Sti flavour, but to do this without ending up with a rough ride around normal roads is not simple

The track pro who I invited to join me at Castle Combe.. was astounded how good the car was and we pushed it to the limit and beyond... to gauge just how good Brumbrums spec c is... He was amazed at how fast the car was around the circuit and it put much faster and more powerfull 'track' cars to shame

In the real road world I am confident this car would muller anything, then head but it, stamp on it's face, rip out the spinal cord and then give it a nasty chinese burn for kicks

If anyone, and I mean anyone, would like disagree with me.... then you are I am affraid a fecking know nothing knob gargler

Now when it comes down to it... with the right set up Scoobies are the dogs

Dont waste your money on a bit of this and a bit of that.... do it once and do it right

Cant vouch for the customer service or quality at Powerstation as I have never used them...

Now who wants a fight down the pub? or anywhere else for that matter
