can any one tell me if a set of 17"speedline chronos will fit over 4pots, the wheels look very similar too rb5 alloys kirby32

 

Obviously the diameter is ok,but the offset might be wrong,small spacers might help 3-4mm

 

Yep - don't think they'll fit as standard. I had some over 2 pots ok but was told they would'nt fit over 4's without spacers.
Alas

 

where can i get these wheel spacers and would i need diffrent bolts

 

Most wheel/tyre suppliers will be able to supply them, and you will need longer bolts as that's 3-4mm of the bolt not being threaded in!!!

 

3-4mm will not do (you can get away with orginal studs with that size spacer as some of the stud goes into the bolt head which isn't threaded about 3mm or so). You are looking at 7mm minimum. I had some of those wheels and in the end moved to prodrive ST2's due to the problems of getting them to fit over 4 pots.
