sorry about this, probably covered a thousand times, did a few searches but still not 100% sure:
got a mk3 8v gti with the standard 15" longbeach alloys running 205/50/15 at the mo. Have just bought a set of mk4 15" TDi alloys off ebay (funnily enough i've seen them on some sites listed as Longbeaches too?!) nice looking alloys, seen a few pics of them on mk3's and look nice.
Anyway these new 15" are ET38 6J. What are my options for tyres without putting my speedo out? Am i right in saying just go with 205/50/15 again? can i do 195 like on the older golf mk3's, as they are cheaper? and secondly am I going to need spacers or anything?
First time changing alloys on a car!
