ET question

[AtomicRex]

Ok... confuzzled now... basically, what is the max sizes I can have from a 15" wheel for front and rear on an FC

 
Time to get your tape measure out!
 
Measure the current width and offset of your wheels.
Next measure the available space back to items such as your dampers whilst the wheels are straight....then turn them lock to lock and check that the extra width doesn\'t knock against the inner arches, suspension or damper. Then measure the available width back to the edge of the arches so that you aren\'t showing any tyre.
 
Do this front and rear and post back the measurements...then we can calculate the available width and offset.
 
Personally I would go to a 16" rim...we are doing an FB project at the moment, and the available discs and calliper set ups are minimal for the 15" rims. We are fitting 300x32 discs on a 4 pot calliper on the front with 16" rims
 
The good thing about having the wheels made is you wont need spacers

Personally when working it out, I looked at what offset my wheels already are: 6.5J ET38, turned full lock, I have space and it clears fine.

Therefore if I get the outer lip banded to 8.5J I have an ET of 15, but the back space is exactly. Doing this means I KNOW I have clearance. (as said the rears will be 9.5J ET0).
I worked it out by using an \'offset calculator\'. Try to keep the backspace as similar to standard wheels as possible, then go outwards from there!

You do need to careful with just adding out...
 
The cars geometry has been worked out using the standard wheel.  By just going out you wont necessarily be using the full width of the wheel....and so will need to add camber (or remove as you are adding negative).  Be aware as you are going to be changing the way the roll centres work, the bumpsteer may get worse....this is just at the front...the rears arent too much of an issue as they dont steer

well, I have 25mm spacers front and back if that helps at all?

It\'s not what I promised, but this will do for now. Bear in mind in all photo\'s I\'ve just dropped the car down, it hasn\'t been moved, if I\'d moved it the ride height would have dropped slightly and I\'d not have positive camber!

The wide ones are 8J ET-10 (standard rears for widebody Starions!) and the others, I think, are 7.5J ET20.

With the right choice of tyres and lots of arch rolling the Starion rears WOULD fit, but for now I\'ll just run the fronts on the front.

finally the pics come out.

looks like you got quite  bit of work to do

wheels look sweet though

Yeah mate, I\'ll have those Starion rear wheels on there some day! With some arch rolling and 205 tyres instead of the 225\'s it should happen.

Still planning on getting the steels banded though. But they\'re on the car, and can\'t get them off till I have other wheels ready to run.

Damn, where can I get a set of those wheels? I guess that the arches won\'t need rolling if about an inch gets cut off them? The flares will cover them (after being re-welded obviously). Will the rears fit ok after that happens?
