Default What shocks?

I have noticed that the front of the car, despite being very low is very soft at the front(i.e. feels a bit bouncy). If you push on the corner it doesn't just bounce back and settle, it rocks a couple of times, (reminds me of american police cars in car chases lol), so I am thinking the shocks need doing.

Any recommendations in what to get??

Scott has the Prodrive Bilsteins on his and really rates them, but think they're rare to find.

I had the same problem on mine - when removed, they didn't return at even speeds after a compression, and one of them didn't return at all. Went with KYB Ultra SR shocks and a new set of springs, difference was huge.

Camskill are a good place to get them from, probably looking at £300-400 for a set of 4.

I may be able to get Billies but for around £650 a set.
KYB AGX adjustables are also around the £650 mark, but I found these too hard even on the soft setting, on Eibach springs.
The billies are a different league compared to the KYB's though, as they use inverted 40mm inserts and are re-buildable.

Will do Alyn, when the set I have arranged for Duncan arrive........
I'm also going to try and get the ratings off the shocks, which I am lead to believe are marked at the top of the 40mm insert, to ask (or maybe you can) bilstein what the preferred spring rates are for them.

Where are the part numbers, are they stamped on the strut as I may be able to read that off mine which are on the car without disassembling the top mounts.
Actually IIRC they may be on a label on the rear. Will have a look.......

the shocks are normallt on the strut itself as that is the "assembly" number, the top of insert may also be marked but obviously just refers itself

as for springs i am in protracted discussions to hopefully have an Eibach "special" which will be as near to the P1 kit as we can get without infringing any copyright or political boundaries...............

Would it be possible to get close to the P1 spec but lower the ride height to similar to the tein stech ?
I have just tried P1 springs on bilstein and although the handling had less roll then the teins (which I fitted a week earlier) the ride height was too similar to my previous eibach sportlines to warrant keeping the P1 springs.
The P1 front ride height was exactly the same and the rear was only 7mm less, hence I switched back to the S-Tech.
The S-Tech are 15mm lower on the front and 25mm lower on the back compared to the Eibach sportlines, but due to their softer rating are actually taller/longer when compared off the car, then the P1 Eibach's
I would want the matched spring (or as close as) to the Bilstein which I think is the 'WR Prodrive' spring provided as an option from 1998 to 2000 on the Bilstein suspension upgrade (Page 12 of : http://www.subaru-impreza.org/downlo...F%20MANUAL.pdf)

Perhaps we need to find the spec of the wr springs ?
I have swapped broken ones of these on a friends 1998 WR Spec car, for s-tech teins and the ride height was pretty much the same, although the ride firmness ended up a touch softer, which would make sense when you see the Tein stech spring rates of 179/179lbft.

i think thats the kit i meant to be fair........................

as for specs, i have to commit to 50x sets so not exactly a minor task / commitment, hence the on-going discussions

WR Spec springs would be great, even finding out the spec's would be a step in the right direction.

The P1 Prodrive Red Eibachs are probably matched to the Red P1 shocks which I think are 40mm inverted KYB's rather then the Bilsteins.
The P1 guy's want them as I think now their 13+ years old the original fitted by Prodrive are snapping. Although they may also consider the WR spec ones if they know they lower it a touch.

I had new KYB's and new Eibach springs with whiteline drop links fitted to my old wagon, after someone recommended the setup, they drop the car about 15mm from standard, not very much but enough to set the car off.

The above transformed the car, It handled amazingly well, not too stiff for our bumpy B roads as alot of setups can be... (my coilovers on my newage for starters!)
Add a set of camber bolts for the rear and with a full Geo setup in a classic you are living the dream in my opinion., anything stiffer is compromised on our crappy roads.

I still think that wagon handled better than my current car, I certainly had more confidence pushing on up twisty welsh mountain roads.

Speak soon!
