Pics & Review of My Bilstein PSS10 Lowered Red Turbo by cannga

sanheim, thanks for the feedback. I almost corrected your "cero" spelling until I realize where you are from :-). Anyway if you could pls give full review of Eibach spring when you have a chance since I think you are one of the very few people on this forum who have it. 

And yep your observation is why I've often mentioned the Tarett drop link is, BY FAR, the most cost effective mod in our Turbo. Anyone who is interested in learning and experiencing what a stiff link does, this is the one to try. So cheap, user adjustable, completely reversible, sinfully fun to play with.  http://www.tarett.com/items/996-997-...lnk-detail.htm

Links with metallic joint, whether rear toe link, or drop link, etc., reduce the play of the suspension system and that's what you are observing. BTW, an after-market drop link also increases the effectiveness of the sway bar; middle setting of sway bar would become somewhere between middle and hard, etc.

The stiffness should increase only mild to moderately. At lower setting, in theory sway bar & related components increase primarily roll stiffness, as opposed to stiffer spring, which would increase both roll stiffness AND ride stiffness. (In practice, at higher settting, the stiffest setting of the GMG sway, the sway *does* add to ride stiffness as well, quite a bit in fact such that I've never used it in my Bilstein car.)

What's most noticeable to me is that when you hit a bump, car would make a slightly louder and higher frequency thud sound.

Saw the video; my God looks like someone was having fun.  

I highlighted the part that emphasizes how much work (and $$$) is involved for the various track junkies on this forum. And how, no matter what you change and what you add to your cars, for serious track drivers the ultimate judge of success will have to come down to an improvement in track time. This is a lot more work than for street drivers, who are happy enough just from the subjective improvement.

Saw the settings of your car, wow, toe out setting in the rear - for the advanced drivers no doubt. I understand front toe out but the rear toe out - could you pls explain why it was used?

>>>>>

Front camber: -2.7 per side

Front toe: +0.05' total

Castor: 7.5

Rear camber:-2.3 per side

Rear toe: +0.34' total

Walt, this is an excellent post that touches on several important points of suspension tuning and a perfect summary of my interminable rambling over 4 years. :-) Some of the points you mentioned, less weight transfer (from lowering), less body roll and squatting/diving (from stiffening), and speed of transition of weight transfer (from stiffening - rarely discussed) are key principles and the reason why "stiffer and lower" is the mantra of supsension tuning regardless of cars.

One comment about why our car didn't come this way - it's because a lot of people want a softer more comfortable car; there is nothing wrong with this - personal preference. Second, Porsche makes GT3 and GT2 for the race track, and it's their philisophy, since 996 and 997 anyway, that the Turbo is going to be the soft grand touring car. This is why if you go to GT3 forum they have such disdain for the Turbo suspension. Yet, the philosophy works out perfectly as their financial success is proof.

I too feel that for the Turbo, suspension mod is the first thing that should be done. The whole point of this thread is to let new people know about the middle ground that could be so cheaply achieved. :-) On a scale of 1 to 10, if 1 is stock Turbo, and 10 is the GT3, then Bilstein is the 5, the middle ground that brings the car to be THE perfect daily driver. IMHO, probably the best street-track combination car that Porsche, or any company, has ever built to date. For this reason, my next Porsche will be an addition to my garage, not a replacement; the Turbo stays forever - true love LOL. Kidding aside: fast, agile, pretty, perfect seating position, perfect outward vision - what more could I ask for?

PS 

Walt: Turbo S PDK with Bilstein and R compound: Wow, great and fast, very fast, car. Drive safely.

pwdrhound: sorry not fully awake yet.
