Alloys question, yes... another Offset related Q, sorry. Options

[MisterRay]

recently i drove into a pothole, the size of a speed hump (somehow the speed hump that used to be there... went missing, no lie) and cracked/buckled my alloy. I have currently got my eye on a temporary set on eBay and was wondering if these specs/numbers are fine for the car. will they fit without rubbing/hitting arches? is it going to affect speedo? etc. (its the offset that gets me)

PCD: 5X100 (i know thats fine)

RIM: 7x17 H2

OFFSET: ET 45

CENTRE BORE: 75mm (will get spigot rings)

TYRES: 215/45/R17

any info would be much appreciated!

That's correct. I have 7" +45 offset wheels on my car with 15 mm spacers, so essentially +30. The front wheels are barely tucked but the rears could use a bit more spacing. I had to roll my rear fenders.

So if I was to use 10mm spacers which would I use? There seems to be bolt on 1s which are almost 5x more than the 1s that slip over the original bolts. Which ones are u using? (sorry bwt all these questions, interior is more my thing)

It depends... haha

for +10mm you would want slip-on ones. The annoying thing with slip on spacers though is that you need to install extended studs which can be a bit of a pain and certainly adds up the cost!

Hub-centric bolt on spacers are preferable IMO. However these are pretty much minimum 15mm, but commonly just the 20/25mm ish size. Problems with these are that if it is not big enough then the original studs poke through the spacer and if the wheels are multistud or don't have sufficient space between the studs then the wheel won't go on and you will need to cut down the original studs!

With those wheels though I would be going (Front/Rear) +10/15mm for a factory look (i.e. a bit sunk, but not too bad), 15/20mm for practical flush (this is what I plan eventually) or 20/25 for proper flush.
