Good choice. A group email list I'm a part of with some other local owners also recently brought up the Bilstein vs KW topic, as someone was looking for recommendations. One owner with two cars and a set of Bilsteins on one and KW's on the other chimed in to give the KW's the nod of approval for multiple reasons over the Bilsteins.

 

Thanks BoomBoom, appreciate the feedback.

 

Thanks Ghassea, there are so many ways to slice up this suspension upgrade, it’s mind boggling

 

Could you share the points? It’d be interesting to see.

Here’s what I read when making my choice for pss10: http://www.jackals-forge.com/lotus/993/pss10/pss10.html

 

the biggest pros cons i have heard boil down to long term customer service/support (bilstein hands down) vs better fast bump compliance (kw). The bilsteins to me have too much hispeed compression damping so over sharp bumps they are quite stiff or force you to soften the adjuster so much that you lose control. They are great on a smooth road or smooth track. But bumpy is not good and for a street or double duty car thats an issue. I know motorcycles better and prices for really great suspenders are affordable. You only know the best you have ridden (or driven) so personal recs are always subjective. A great suspension is both controlled and compliant.
betting motion control may be best combo.

 

Thanks for the additional info. My driving roads are pretty bumpy, with lots of frost heaves and other lumps and bumps. I find the PSS10 to handle uneven pavement really well. I agree with Jackal’s assessment that at slower speeds they can feel a bit harsh, but once up to speed they feel quite composed and the car handles great. Much better than I remember it (or my old 964) on stock suspension.

 

Am sure that is true. From old threads there used to be a Ruf PSS9 - with custom valving and people raved about them. No longer available from Ruf. But am sure someone with the right mojo could rebuild with the magic custom shim stack

 

Bilstein will custom valve at there shop in Poway, CA.

I have Bilstein SuperCup units front and rear that were originally valved for 1200/1200 lb/in springs, my springs are 450/624 lb/in and Bilstein managed to match the damping to my cars weight and spring rate nicely.

 

I’ve had bilstein revalve for cars in the past. It’s a great service.

I have a 95 911 C2, I do HPDE's 2-3 times a year and lots of mountain driving in CO. I did my suspension upgrade in 2 phases, but should have done it all at once ... about 8 years ago I went with Bilstein HDs, corner balance and alignment. An improvement over the stock setup. A bit harsh on the street and not quite what I needed at DE's. About 5 years ago I went with the current setup ... PSS10's, stock bushings, ER rear drop links, M030 front ARB, RS adjustable rear ARB, race alignment and corner balance ... the most important part was having the work done by Chris Cervelli. He tailored the setup to how I was driving and my budget.

This setup allows me to "tighten" it up for DE's and "soften" it for street/ mountains with a minimum of adjustment. Stock bushes and stock shock mouns work fine for my driving. I went with Biltstein to stay in my budget and have never regretted that decision, the KV's were tempting but I decided to concentrate on improving my driving.

If I were to do anything different today I would look into revalving the PSS10's and maybe use the ER Sport bushes. I run at about 5 mm above RS height, I did not replace my carriers or tie rods and do not experience any "bump steer" issues.

I realize technology improves, so newer options are available and everyones driving is different, I just wanted to share my experience ... good luck with your upgrades and please post what you end up doing. I like to read about how these different upgrades are working.
