Hello
I have just finished 3 full days of racing in Poznan, Polen. My SPF is completely standard as delivered from the factory, with Roush 427R engine and ZF gearbox. Wheels and tires is as delivered from the factory (15" with Yokohama AVID tires)
The car got a really beating for theese 3 days on the track (and also a bit off the track). The only problem I expirienced is bad tires. This I knew up front and was no suprise, but I wanted to test out the car before I decided what changes to be made. I drowe the car on the road down to Poland and back again (2200 kilometers all in all).
This is a summary of my track experience:
Tires
I will get a set of 17" wheels and better tires.
Brakes
The original brakes is more than good enough using dot 5.1 brfake fluid. I drove 20-25 rounds without pit stops on this 4 km long track without any touble with the brakes.
Cooling
We had temperatures of 30 degrees celcius and the car was never overheated. Oil cooling is also wery good. The only problem is that the electrical cooling fans is running all the time when the temp is above 90 degrees celcius. When having several trips off the track and into the "bush" it easily comes stones and dirt into the fans and this broke one of my cooling fans. I will redo the power supply for the fans so that I can turn them off when going round the track.
Suspension
I think the original suspension is good enough for track use, but of course a set of fully adjustable shocks whill make it even better. I know that Wilbers is working on making a set.
Others
The only thing I have found to be of bad quality on my car is the window wiper. There is a wery simple and bad solution for connectin the wiper arm to the rod. I need to improve this. Apart from that the car seems to beg very good put together. Even with the wery bad tires that I had I was able to keep up with Ferrari 430`s, Vipers and a variety of Porches that also attended this event.
