Hello guys,
I am currently away from my vehicle and was wondering if some of you guys could help me out. Was just wondering, on my 02 wrx if the hubs would allow for 15mm spacers(disc type spacers) to bolt straight on or would I need longer hub bolts? Has anyone done this? What are your opinions?

Thanks

In my opinion spacers are a waste of time, money and when used with anything other then light street driving can be dangerous... 15mm spacers are just daft and you will want new extended bolts.

It isn't mentioned but either way you go you want the hub bore size to match your perfectly, in the case of a 2002 WRX a quick google search found 56.1mm.

TL;DR - Save your $$$ now and buy wheels that fit. If you are set on spacers then do you research on the manufacturer, material / metal used and user reviews so you don't end up like this

As far as I know you only start talking extended wheel studs when dealing with slip on spacers. The factory wheel studs are designed for a certain wheel centre thickness and factory nut thread length, and adding a spacer on reduces the amount of thread engaged by the nut - can lead to thread stripping etc. if not enough is engaged.

My 2c; get wheels with the offset you're after. Spacers aren't legal unless fitted from factory so it's just another thing that can be picked up if they're noticed. If you have to get them, bolt on hub centric is mechanically better than slip on (still can fail as Dan has pointed out, however.)

Dodgey.

If they're a good product and fitted/sized properly, they're absolutely fine. There are plenty of examples of people who track cars with spacers with no issues. Yeah they're illegal on a road car, but so are most of the other mods most people do to their cars.

Perrin do a good set, but as Dan said above, make sure the hub rings fit perfectly to your hubs.

i cringe when i see those pictures above - looks scary as f**K but I'm sure a good quality space would be no problems, obviously illegal but you would have to use bolt on spacers, especially for 15mm. don't use spacer plates etc that shorten the length of threads in your wheel nuts as said above!

U need go for 20mm+ bolt on spacers to avoid grinding oem studs. Perrin does have them. 450 shipped.

I had 5mm slip on spacers on my back wheels to clear the coilovers. Did quite a few track days with no issues. One experienced mechanic told me it was a bad idea and a experienced racer told me that up to 5mm would be fine.

Torque your spacers and wheel nuts with a torque wrench don't over tighten them.
Use the correct nuts conical or flat back . Don't buy cheap shit .

If you have an accident and insurance finds them don't expect them to pay.
