Rims & Spacers - help needed

[stolly]

Howdy all, I just need some advice on using spacers for rims. I am looking for a new set of rims for my R33 gtr, I have narrowed it down to a few sets but some aren't the right offset and need spacers. What's the deal with these? Some tyre shops have told me that they are fine, are legal and don't change anything at all, others have told me they are dodgy and illegal. Do they change the wheel track, or have any adverse effect on handling etc. Any help will be greatly appreciated. Thankyou

As for the legality of them. I have spoken to an engineer and even if they are the bolt on one's they are still illegal. If you have to have them i would get bolt on's as they are more secure but i don't like using them at all. Your better off waiting and finding the right offset for your car.
