Personally, if it was me, I would choose rear wheels that gave as little clearance agaisnt the chassis as possible, and I would leave the front end as it is in the book, knowing I could always make some adjustments later if any problems showed up (which I bet they won't).

Wider track at the rear causes understeer wider track at the front causes oversteer.

Most sensible thing to do is ditch building a kit car and buy a vw camper, transport and a roof over yer head at the same time..because next year the powers that be will ban houses along with thinking for yourself;)

the dax rush i had had huge 255x40x15 tyres on the back and the track was if i remember right about 50mm or more wider EACH SIDE than the front. there was no handling problems with it at all - the only thing that you really have to watch for is remembering you have a wider rear end than the front! reason - your blasting along a country road - in this instant kirkstone pass in the lakes - narrow road - car comes other way - you gotta squeeze over to the left a bit - the front wheels miss the big rocks on the left but does the rear? naaaaa of course not - it can stop the car dead from moving..

so iv heard.. baaaaaah... :rolleyes:

Why not make the car with equal front and rear track... perfect time to do it while you are building it..?

to late for that the wheels are nearly on. I am using 7j rims which will need 2" spacers as they currently lock solid to sb1 and d11 when bolted on.

Ford Capri wheels on the front will increase your track width considerably as they have a negative offset.

Easier than making different suspension, and fit straight on the sierra hubs.

I even have a pair you can have for nowt if you want them.

Hmmmm....
I got a Tee shirt as well;)
