Hi Oliver,
The base car which I plan to use is a pre-'74 1303. It has early type McPharson struts. I do not intend to swap for a complete 944 front setup. I just want to adapt the 944 spindles with late super beetle control arms and the Kerscher 17mm ball joints (Kerscher webpage mentioned that it is for fitting the 944 spindle. I just guess the meaning because it is in German). I just wonder if the 944 S2 spindles and early 944 spindles are using the same size ball joint.
As for the rear, I am not sure how to make the spring plates with CNC-machined mounts and unibal mount in front from sketch. Do you think I can use some real or aftermarket 935 spring plates and modify to fit the bolt pattern of the 944 trailing arms? Does the bolt pattern of 935 torsion bar cover fit beetle rear torsion tube bolt pattern?
Is the Kerscher front coilover struts suitable for track racing? Any good suggestion for both front and rear racing coilover? What spring rates should be used?
The race organizer told me that the circuit which I intend to race is not quite suitable for a Beetle because there are many corners. He said an average group N race car, such as Honda Civic EG9 can do 2 min per lap (4.4km a lap). A Porsche 993 racer can only do similar time due to its heavy tail. He guessed that a Beetle with a very unbalanced front/rear weight distribution can't do better than 2.5 min. So, I think I should pay more attention on front/rear balance. I will move the weight torwards the front by using fuel cell which can be fitted in the front spare wheel well and by relocating the battery to the front end, and will also lighten the rear end by using carbon fibre decklid, etc. Do you think this will work? Also, I guess I need the best brake system to allow late braking in corners. Which system do you think is the best to do the job?
Thanks for your professional advices.
Tim
