My GT3RS project car now has the Intrax 4-way overs installed and tested over four track days. Result- AWESOME!
The more I tracked my 2010 GT3RS the more I knew I wanted a more track oriented suspension set-up. Upon replacing the monoballs, drop-links, caster pucks, toe-control arms and top shock mounts with solid bushings, the car was much more precise but still too mushy on track. Trying to research a new coilover solution was tedious and time consuming and I looked at a lot of choices, and talked to a lot of people.
Bottom line I selected a supplier most USA folks have never heard of - the Dutch company
Intrax. Located in the Netherlands, Intrax has a LOT of Porsche GT3 set-up experience. I chose the 4-way with spring adjusters on the rears and "Black Titan" piston coatings to help reduce stiction.
Intrax required me to specify my suspension set-up, primary use of the car and current handling and then built the system to my specific needs. I requested track performance with the ability to still be street driven if desired.
Many smart people shook their heads poo-pooing my decision and warned me that I was was about to ruin my car. That only Porsche could properly chose spring rates and dampening. That 4-way adjustable would be a tuning nightmare.
WRONG!
The result, upon replacing the PASM OE system was amazing to me and quite simply a transformation. Installation was by Jess Lattin, a talented Master Tech I work with, was straight forward and problem free. Out of the box, with Intrax recommended set-up settings, the car was transformed to go-kart like handling. Turn-in, track-out, steady state, stability under braking, trail braking, all were greatly improved.
Over the course of 4 track days at two very different tracks I was able to experiment with various compression and rebound settings and was able to adjust for very bumpy and then very smooth tracks easily and quickly. With the car on the ground.
I will update the thread as things progress but so far I could not be happier with my Intrax coilover solution.
