15 inch down to 13 inch, what difference wil it make

[Lardy]

Hello, I'm looking for a set of track day wheels. The car is a Roadsport SV 165BHP, De-dion axle. It has 15 inch wheels on it at the moment but I have seen a set of 13 inch at a good price. What difference will it make to run the 13's as opposed to 15's?

 

Thanks

Depends what tyre size you run on each set of wheels... If you keep the same width and profile you'll drop the ride height by 25mm

 

Cheers

If you went to 13" with 70 profile tyres then there's almost no difference at all, with 60 profile you do loose a bit of height but at worst it would be 1" (ie half the size difference) assuming the tyres are exactly the same size (which is highly unlikely).

 

CR500's will drop it a bit more as they are lower profile than say 021/048r's
