Ah sorry, knew it was a V4 but got the wrong one!

The reason I ask about tyres is that on such a light car, low profile tyres can really hurt the handling, big wheels for show, small wheels for go

mhhh...

I think i can be lucky that i have an bike with overdrive in the box...

Think its time for 55 tyres and an 3,62 diff....

In this setup it tops out at 168Km/h hitting the limiter in top gear!

but at cruising (would be main goal for me, daily use)

i need 8400Rpm for 120Km/h max speed here.. think the fuel consumption will be high at that engine speed.

If i fit 55 tyres and an 3,62 diff.

It will top out at an nice 195km/h (hitting rev limit)

And 7200rpm for cruise speed (120Km/h)

Can anyone confirm this?

if this looks to much for my engine (782cc) then maybe 3,62 and 50will be the combo.. 189Km/h hitting limiter and 7500rpm for 120km/h....

What tyres do we use over here???
Chris??

If you download the spreadsheet I use from here, just edit it for the figures you have for your engine and tyres etc, and it should give you a good idea.
