Chris Harris + Excellence = must have issue! Can't wait to read this article.
IZZONE: I agree with Chris's comments: your 997.1 RS is probably the worlds greatest! However, I would add TCSRACING (Tom) to that statement.
Love the vid & the overall racing pedigree.
Exe-tc is really developing a reputation in the world of suspension.

The trouble with my tarmac shocks for street is that they tend not to be soft until under load thus city driving they would still appear stiff.
For track there is more sustained G-force load and at higher speeds. This is where Im curious to what the result would be with grippy slicks? Would it be too soft with all the g force and available grip?
Would it upset the chassis dynamics and suspension alignment under full load in a corner?
My track only Bilstein Setup is stiffer then my rally shocks and stock shocks and when they are lowered to CUP ride height there is little travel but under full load of g -force in a corner the car remains balanced/neutral. I cant help but wonder if it was too soft would it squat in the rear especially under hard acceleration out of the turn causing the the front end to get light....

Three Wheelin'
Ouch, more than I was hoping to hear.
It's not as if replacing the PASM dampers would be cheap, but I was 'hoping' for a number closer to $6500.
Thanks

Hi Guys,
There are many interesting perspectives and opinions about suspension. I will try and explain the Exe-tc concept which is a little different from traditional beliefs about suspension technology. Exe-tc has not reinvented the wheel regarding suspension. But they do have a different philosophy compared to most other suspension manufacturers. This approach has proven to be very successful. Exe-tc has provided the suspension for Sebastian Loebs' car which has won the last 8 World Rally Championships. They also have provided suspension for people competing in rallies all around the world along with cars in formula one, British touring cars, Australian V8's, and the VLN series at the Nurburgring. They only sell shocks and springs as a package as they believe that the two work as one. They replace the normal stiff linear spring with a much softer progressive spring and then control what the suspension does with very powerful dampers. Interestingly enough, the suspension package that they build for Porsche's are identical with the exception of vavlving for both road racing and rallying. As an example, the GT3 Cup Car that is running at the Nurburgring in the VLN series and the GT3 Cup Car that is running in the European Tarmac Rally Championship are running the same suspension systems, same springs, same shocks. Obviously the ride heights are different and the setup is different but the suspension package is the same.
There is very little difference in grip between the slick tire that they run at the ring and the rally slick that they use on a tarmac rally stage. By making the spring rate softer and progressive the tire maintains better contact with the track surface. You also get a significant improvement in tire wear with this setup. Good suspension is all about creating driver confidence; this allows the driver to push the car to its limits with confidence that it won't bite him (OR HER) in the ***. Certainly in the case of Sebring, with its bumpy corners and aggressive curbs, compliant suspension is a great asset. On virtually every track compliant suspension is a huge benefit to the driver. When you first drive a car equipped with Exe-tc suspension, you may find it a little soft in comparison to what you are used to. As you start to explore the suspensions capabilities you will realize you can do things with the car with complete confidence that would have previously upset the chassis and made the car nervous and twitchy (the kind of twitching that causes some specific muscles to involuntarily tighten). To answer to the question about cost, an Exe-tc 3 way adjustable system including springs is 10k. This is by no means inexpensive, but most certainly value for money as the transformation of a GT3 is remarkable! They also have a single adjustment shock with the same spring available for $6500

Curious what others think about Ohlins? They have completely separate circuits for for compression and damping, which I believe is unique in suspension world, and said to be an advantage.
