Spacer? on z-stech OEM 19's
 

So my plan was getting 25mm all around on oem ray 19's dropped on z s-tech. The only thing is im scared that i will have to roll my rear fenders which is not the path im trying to go. chriscollins did exactly what i want to do https://g35driver.com/forums/brakes-...d-springs.html but than other ppl are saying just on z h-tech with only F-15mm R-20mm will be the farthest you can go before rolling. You guys think 25mm all around will be fine or should i go 20mm all around or 15-20??
