Nice to see the progress on your 'track car'. Some serious work has gone in to it all. Let us know how the suspension from Protlum behaves. Didn't know it so did a search : http://www.protlum.eu/index.html
This cage on photos is not finished yet, few things there will be added.
Plan is to make cage in Imola Red from BMW, and interrior in this yellow like the car.
I bought two Sparco Pro ADV
Set of Sandtler Red harnesses
Sparco steering wheel
Than Protlum Suspension
Quife
Than we will try to do something with gearbox ( any ideas what can be changed there?)
V6 Airbox will also be there
Removed all cats, and ECU Remap by K-Tec
