I have a set of Eibach 30mm spacers that I may consider selling. Are you sure you want to go 30mm on the front? I have 20mm on the rear of my car now and have tried the 30's on the rear just to see how they look. The 30's will move a 7.5x17 Brabus wheel to the very edge of the tire lip even with the factory one inch wide lip extension. I would think a 30mm front spacer would move the tire past the edge of the fender. I have Brembo caliper covers or I would mount one of my 15" wheels on the front with a 30mm spacer and take a pic so you could see how it looks. With the caliper covers, I need at least a 16" wheel to clear them.
I have some pics in my gallery of both 20mm and 30mm spacers on the rear of my car for reference. I have looked into many brands of wheel spacers and find the Eibach line to offer the best product currently available. Look at their website to get info, but go to "Auto Anything" to get the best prices on Eibach products. Good luck with your mods.
