I have just completed an autocross season competing with my 944 in stock form. For this winter’s project I would like to make some modifications to the car suspension. Last winters projects included:
Koni yellow shocks
Rebuilt suspension wear items with stock components.
This car is only used for autocross and not really driven on the street so comfort is not a consideration. In fact next year I am planning to trailer it to events.
My thoughts for improvement include front lowering springs.. not sure of a suitable spring rate.
Rear suspension could include removing torsion bars and replacing with coil overs. Or a combo of increased spring rate torsion bars and coil overs. Again not sure of what overall spring rate I should be targeting.
Anyone have experience with this. Any ideas would be welcome.
Depending on your budget, I would suggest the following in order of priority:
1 – Check and replace any worn suspension components such as ball joints, track rod joints, etc..
2 – Replace the front and rear (if you have one) Anti-Roll bars with those from a 944 Turbo.
3 – Replace all bushings with Polyurethane bushings.
4 – Fit Adjustable Shock Absorbers.
5 – Lower car front & Rear (various ways to do this with stock or lowered springs/torsion bars or coilovers).
I’d recommend that you talk with a local Porsche specialist that has racing/autocross experience for their suggestions.
