Tyres

Would and 18" wheel be ok for track? Im only doing track days for a hobbie, but want to make sure its all done properly!

What's the minimum size of wheel you can fit to your car?

Now find a light wheel in that size that is appropriate for your car.

There's the size of wheel you should be running for track days.

Now find an appropriately-sized tyre, probably 40-50 profile in a track-day compound and tread pattern and put it on those rims.

Done.

Probably 16" rim in 7-8" wide, running something 205-220 width.

Really big wheels are just for poseurs.

I agree. I found the smallest diameter alloys that would fit over the brakes with a decent gap for cooling and then fitted stock width (R888's at 225 for the MKV) works VERY well.

Meh, the gap for cooliing's pretty immaterial, given that you've got wheels with gaps flying around all over the place.  So long as a fag paper will go between the caliper and the rim it'll be fine - a couple of generations back the M5 actually had wheels that worked like fans to push air past the brakes.  Always though that was particularly neat.

What is the smallest wheel size/offset that will fit the dated Golf5?

As a guide on weight, the Team Dynamics 15"x7" rims I run weigh 6.6kg each.

[Hurdy]

I've not tried 16's on mine, but I doubt that they'd fit given that the caliper gap to the inner wall looks less than 1/2". The offset could drop to 35 from 45, but then I'd guess the inner arch/ struts may become a worry.
On a stock GTI the calipers are fairly chunky and I doubt you'd get a 16" alloy on there, but it would be close.

Dated Golf 5

My 17" Team Dynamics come in at 8.2kg.

Debating on whether or not to get some OZ Alleggerita's at 17x 8 as they come in at 6.9kg each.

the problem i have is that i am running a 6pot porsche cayenne turbo brake set up on the front, so i cannot go any smaller than an 18" wheel!

Just out of interest would having a wider wheel on the rear help handling? For example a 9 or a 9.5j?

Thanks

Your car is probably over-braked and you're suffering from an overdose of vanity.

Take off the tart brakes and put something more sensibly-sized on.

Wider wheels on the back will make you look a proper charlie moron.

Jake did you decide on what tyres you are going for? Can you not squeeze 17s over those brakes?
I am now hunting around to see if I can find a set of 16s that will go over mine.

is it RWD tyer smokeing monster ?  no 

for the handeling just get it 4wheel alinged.    you can make the car tighter or looser buy pissing about with camber and stuff
