Yeah, -2.5 front and rears is what worked for me before, that's why I decided to start from these as base line... wider tires with same roll stiffness might call for more camber, but with good caster angles I have now car is gaining more camber when steering is off center then before. We'll have to wait for trackday to find out for sure..
In the meantime I started removing dash to delete remains of AC system and sort out the wiring, and my worse forecasts came true.. I managed to spend only several hours on Saturday with the car and now it looks like this:
And pic under the dash shows how things are done there, I haven't done anything to make it look worse.... yet. ))
Instrument cluster is what made me stuck right now... Car has cable speedo and it seems that it needs to be disconnected from gearbox first to get dash out, which called for removing intercooler and some other stuff that was in the way..
I have electronic VSS laying around, and V4 ECU will be happy with it, I believe, but then I'll have no speedo reading on my V2 dash.. Anyway, I couldn't remove dash on Saturday and on Sunday some other things got priority, so car left undrivable until next weekend.. Hopefully... Because the more time passes from disassembly, the more time it usually takes me to put it back together. And also it means more unnecessary parts in the end
Also I wanted to put steering angle sensor for datalogging somewhere and it seems to be more difficult than I expected. I ordered some generic 360 deg hall sensor with 0-5v output, so I need to connect it to steering shaft somehow with 2.5:1 reduction or whatever lock-to-lock turns my rack has now. Any ideas?
