Good stuff, some competetion!
BTW hurdy, you posted up a link about some super duper lightweight bucket seats on these forum ages ago, you wouldnt happen to remember the name of that company at all would you?
As Luke said - Tillet seats. If you get a chance to go to the Autosport show at the NEC in Birmingham, then they have loads on display from different manufacturers and you get to sit in them all to see if they fit and how comfortable they are.
Competition eh Pov?
I think the way forward for the RS3 would be a good diet for starters
1575kg is a little lardy, so if I can get some lightweight seats, battery and wheels on that should drop the weight substantially to at least 1570kg
335bhp and 1.575t = 212bhp/ton
Add a stage 1 remap
403bhp and 1.575t = 256bhp/ton
Lose some weight (approx 50kg)
403bhp and 1.535t = 262bhp/ton
Then stage 2
435bhp and 1.535t = 283bhp/ton
should help move the car.
The fact that the s-tronic gearbox is rated at 650nm and even stage 2 would give around 580nm means that I should see decent launches with no clutch slip and 4wd.
so the RS3 should go sub 4 seconds to 60mph......hopefully
and low 12's/high 11's on the qtr mile and (fingers crossed)and easy sub 8 mins on the 'ring (B to G).
