Spacer help

[Zeitgeist0190]

Looking at getting some spacers for at least the front end, have read through various other threads but haven't really been able to come to a conclusion.

I'm looking at getting some 25mm delta mics, they might be heavy but the extra weight isn't a big deal for me, and i understand that as long as the bolts are done up right and the mating surfaces cleaned - plenty of people use them with no bother whatsoever.

My questions are: is there a proper way to determine what size of spacer i can use without any scrubbing/rubbing bother? My car is lowered around 50mm on some TA coilovers on 15" wheels which are et38. I don't entirely know what et38 means though and I have a non-sport wings if that makes any difference.

​Can anyone shed some light?

As long as its not going to hit the lip of the arch you should be grand. Thats how i look at it though.

​Might do on a bump and over here, it's all bumps! no idea how far the car bounces when i hit a bump either

Roads are shocking over here! Well you could try, eg 15mm and if it rubs, sell them, get 10mm?

You want the tyre to clear the inside of the arch, regardless.

You could remove the springs from your shock, jack the wheel up while the car is in the air and measure the gap between tyre and arch?

not got the tools to do that above, i may get the dremel out and cut out the lip, or paint and fit a ph1 sport front!

So after a little bit of researching and looking about - i've had a look and i think that 25mms would poke out of the non-sport arches a little - which i wouldn't be totally against, unless it was a crazy amount.
I took a measuring tape and measured from the sidewall to out arch edge and it was /about/ 25mm - this would potentially have the tyre close to/rubbing off the arch lip.
​I'll have to get a better look later on.
