[Heeltoe914]

Setup is full simi tube car 1775 appox, 10 and 12 LSD Boxster brakes Combo of high speed tracks and AX. Driving.


Hi guys starting stage three of the upgrades to my Spyder racecar. I am planning to add Adjustable front and rear shocks. The front should not be such a big deal the shocks on the car now are made by a Company called Carrera Shocks. The front’s inserts are much shorter than a Carrera or SC size inserted shock. It’s about 10.5 inch long. The rears are short about 12.5 “.
If you notice the rear shocks are inverted, I would like to find something that will mount with the shock bolt and damper location. What makes finding a replacement a challenge is that the stub that is welded onto my rear shocks is not commonly done and would have to be done before the shock is constructed. I would think that there are other ways of getting a inverted shock on a 914 using stock mounting locations.
Advice or suggestion welcomed.


Part two;
Another question I have is if you have a track only racecar that ran as a high output four banger with a very good setup, than converted it to a 3.6 which adds some weight & HP what guess would you make on how much to go up on front and or rear spring rates???
I am thinking 50pds per corner just for the weight but I need to add in the hard acceleration and cornering as well. What has anyone here tried?
