Offset question
#1

Im still waiting for my 2002 1.8 T (sport package) and I want to change wheels. The standard size is 17X 7.5 with 235/45/17 +45MM offset. If I go with a 17 X 8 that will add .25 inches to either side of the centerline or an additional offset of +6mm. Therefore I believe I should get a wheel with an offset of 39 or close to it, if I don't want to change the original config.
Is that right ???
Thanks

Just tried the offset calculator
and it's telling me that
if my current wheel is 7.5 inches +45 mm offset
and I was to go to an 8 inch wheel with +35 mm
then
The clearance from stut housing to the inside of the wheel will be 4mm MORE
The outside edge of the wheel will EXTEND an extra 16mm. Does this make sense ????
What effect will additional offset have on a cars ride/performance?
Thanks

I measured the hub mount plane to inside lip and inside sidewall on the following 2 wheel/tire combos:
1)18x8 ET35 SSR Integral / 225/40 Michelin PS
2)16x7 ET45 OEM Sport / 205/50 Pirelli P6000
I got the following:
1) rim - 151.5mm tire - 152mm
2) rim - 148.7mm tire - 154mm
You can see with these combo I get a couple more mm tire clearance inside with the wider rim even though the inside of the rim is about 3mm closer.
How do those compare to your calculator?

Here is the URL of the offset calculator that someone posted
http://toy4two.home.mindspring.com/offset.html
When I punch in the numbers it gives
The clearance from stut housing to the inside of the wheel will be 3mm LESS
The outside edge of the wheel will EXTEND an extra 23mm

Handling...The only negative comment I have regarding handling is some tramlining I feel with the 225 not there with the 205 setup. I dont know if the offset plays any part of that or if it is simply the added tire width.
