Due to some potential rubbing issues, I'm needing to raise the rear of my car (325) slightly, and also limit the suspension travel to less than standard. I'm curently running MTec springs all round.

I understand I can get a thicker lower spring pad, this might raise it by 5mm (depending what pad is there atm). Can I use more than one? If so I would probably bond them together with something like Sikaflex (sp?) to eliminate any potential movement.

Could I use an upper sping pad in place of (as well as?) the lower pad and so reduce the suspension travel that way? Or is there a better way of doing it?

My issue is caused by wheels with the wrong offset (ET12), this wasn't so much of an issue until I got new Toyo T1-R tyres fitted the other day - the edge of the tyre now protrudes further out from the rim..
New wheels, or different new tyres is not an option due to lack of finance!

how badly is it scrubbing? i rolled my rear arches when i had 225/45/17's one and a 40mm drop and that cleared ok. i managed to do mine without cracking the paint too.

i used a rubber covered bodyshop dolley and a rubber mallet. heated the paint with a hot air gun until it's hot enough that you can only just leave your hand on it then worked round them. most of the arch is 'rolled' in profile anyway so this cleared but there are a few places you can get some clearance relatively easily. after i did it, i have it a good cut back and then lacquered the area incase of any hairline cracks in the paint that could become porous. 3 years later and it's all still fine.
