4ltr chim wheel offset
Discussion
i'm wanting to change my standerd chim 5 spokes for a set of 17" wheels but i kneed to know the correct offset for the front and rear, different wheel companys are giving me different offsets so i'd rather ask people that know about tvr's. the car has also been lowered 40mm so i need to keep the exact size to make sure the'y dont rub. thanks, adam.

If I recall, mine were 25 front, 33 rear.
When I replaced my wheels I wanted to keep 7 inch on the front and 7.5 on the rear and I struggled to find wheels with the correct (different) offsets front and rear. I was also told that it was important to get the correct "back bore" which is the size of the hole on the back of the wheel. Most 25 ish offset wheels have a peogeot sized back bore and you need it to be Ford sized. I found that the key was to find wheels which were available in both Ford (35 ish) offset and Peogeot (25ish) offset which had a large back bore and used a spigot ring inserted into the back to close the hole to the correct (Ford) size.
Anyway that was the difficulty I faced, but others have found other solutions. I believe that many just use a standard "Ford sized" wheel, e.g. 35 offset all round and go for a wider front wheel to compensate for the fact that the wheel track otherwise would be narrower with the higher offset as they "stick in" further!
Not really your question I guess, but I thought I'd offer my wisdom anyway!!!

I pondered over this for some time and after making my choice of 17" wheels went to a very reputable firm for suspension set-up to be done [changed shocks aswell] and they said it's splitting hairs and is not really worth worrying about as all they do for their racing cars is to use the 16" rears on the front without using spacers. Hope it helps, as I know wheel suppliers don't.
Bear in mind if you change the width from standard you need to adjust the offset.
