Just don't forget anything above 17"s will lower perfomance a fair bit...
btw:
I get my FD1 in about 10 days... yay for me.
205/55/R16 (Stock) vs 235/35/R19 (Aftermarket)
Speedo reading will be 2.4% slower.
When speedo reads 100k/h, you are travelling at 102.4k/h
Correct me if im wrong
Ok 2% difference is ok.... well im not going for performance or else i would have bought the type R, which isnt to great anyways.
Will these wheels and tyres fit?
depends on the offset... you might get some inner or outer rubbing
hey no i lined up against another FD and looked at there gauge while driving at 60km/h and it was no difference not sure about high speed maybe be the slightest different....but not enough to get booked for speeding....

^I don't even think all FD's speedo's are calibrated at the same level, some may be quicker, some may be slower. I've pitted myself against another FD (Sep 06 VTi) auto as well and at 103 on the freeway, she was doing 105 and we were sideby side on cruisecontrol for about 200m before I pulled back to give way to traffic.
apparently some guy did a test on our FD. If you travel at 106km on speedo, u are really going 100
Which ones do you think i should get

I would imagine it would differ for every sample..Quote:

Im not too worried about the 2% descrepency... thats why FDs come with cruise control...
