I have 2 race cars at the moment.
I started with my 146 way back and built it up trackday-ish over time. As parts needed changing, I changed with the uprated version. Then I got my 156 V6 and did the same... up to the point where guys told me I do quick and consistent times - I should consider racing - which I did.
I took our local series title in 2013
, last year I was blessed with a baby girl
(so very little racing) and this year I've taken the 1st race weekend's win
1st race car thread:
2nd race car thread:
The quickest / cheapest way to make a V6 fast around a track is - in order of cost / benefit ratio:
Weight shedding (read Evo75 post)
braided hosed 305mm front brakes with ferordo DS300 or equivalent pads (I use Endless ME20). DECENT Dot4 fluid (275+degC)
Top strut brace
Bottom sub-frame welded up
Stiffer ARB (at the back at least).
Q2 / Quaife diff
Rollcage - this helps stiffen chassis, but is your safety concern when to do it - push it up the list.
I vote the geometry is ok enough on 156, you gain camber when you drop the coil-over suspension anyway
You can make rose jointed control arms for the rear to set even more rear camber and more aggressive toe out.. need very stiff rear ARB to make use of rear wheel steer in FWD car
