Gavin has explained the Extec shock and how it works, I'll probbaly get it wrong but here is what I remember
They put softer springs in the car and do the stiffening in the damper. With the softer springs the tire spends more time with grip.
that is all I can repeat in a correct fashion.......maybe GT3 Girl can elaborate
Whatever teh Extec does it is amazing, Gavin and Chris were cutting every curb at Sebring that day and the car stayed on line with grip

Exe-tc has not reinvented the wheel or come up with the holy grail of suspension. What they have done is developed a progressive spring that is very soft at the beginning of the stroke and progressively gets stiffer as the spring compresses. They then control how that spring reacts both on compression and rebound with very powerful dampers. Their ultimate goal, as Chris Harris states, is to create driver confidence. When you have confidence in how the car is going to react, you can push hard. Softer springs generally give you more mechanical grip along with improved tire wear. On a track like Sebring with lots of bumps and rough curbs, you can attack them with a great deal more aggression and confidence as the car remains stable and is not getting pitched around which stiff springs have a tendency to do.
Aussie Jimmy's tennis analogy is right on.
If you watch Trackcar's video of him chasing Gavin around Sebring, You will notice for example coming through 17 how Gavin's car is able to put the power to the ground much earlier over the bumps and make some significant gain before the benefits of the 3.8 L engine start to pull the gen 1 car back in towards the end of the front straight.
The debate about laptimes is always an interesting one. You guys sound like a bunch of girls bickering
It's hysterical!You can certainly go a couple of seconds faster on a nice cool winter day when the car is making lots of horsepower and there is plenty of grip. When the track is hot and slippery, mechanical grip becomes even more important. Good suspension really helps.
Below is a video of Gavin in a gen 1 car with Exe-tc Suspension, Sequential Shifter, and Hoosiers doing a 2:20 flat on a typically hot Florida June day. Watch how the car deals with the bumps and curbs. ENJOY!

Very imformative thread.....
As far is Chris Harris.....I've been reading his articles & watching his video reviews for years, even before I knew his name. The guy is brilliant & his reviews helped me make my decision in purchasing my RS.
Thanks Chris....you're the man! Keep the Porsche info coming.

Hi Guys,
You are correct, Chris Harris was running Exe-tc Suspension on his Gray gen 1 GT3. He never had Intrax Suspension on that car. They also used Exe-tc Suspension on the VLN car that he drives. A little history for those of you that know nothing about this company. It is a UK based company, www.exe-tc.co.uk , they have provided the suspension for Sebastien Loeb's Citreon that has won the World Rally Championship for the last 8 years. They have been developing a suspension system for Porsche's for the last 3 years for both racing and rallying. A GT3 Cup Car equipped with Exe-tc Suspension won the round of the Spanish Rallying Championship last weekend competing against full on 4 wheel drive Rally Cars. The suspension has allowed the Porsche's to become much more competative with the 4 wheel drive cars. We have been using the suspension on our gen 1 GT3 RS for the last 3 years both in Rallying and on the track with extremely good results. Exe-tc has taken a different approach suspension wise using very soft progressive springs and very powerful dampeners. This makes the car much easier to drive quickly and instills more driver confidence. The photo above is of the winning Cup Car competing in the Rally last weekend, you seldom see Porsches doing this, especially in the US!
Thanks a million for posting it & all the suspension info..
I have no problem if you pass me on the track......

Seeing that you live in the snowy North, why don't you come to Sunny Sebring over the winter and play. I MIGHT even let you pass ME!!!

I just received and read my Excellence magazine.
Very cool write up on Gavin Riches, Exe-tc suspension setup, GT3RS and Sbring by Chris Harris!
Decribing Sebring he mentions words like small mountain range and the Andes to describe the bumps. Without using the words he found ICE mode as well saying ""receive a dose of infamous brake lockout at the end of the back straight". In the stock RS he drove.
"Mildly infatuated with Sebring" "Makes the Ring look like a Criscket pitch"
Great read, even better when you were there and know Sebring :-)
