Hey guys.. I just installed 19" rims on my g35 '04 and need to replace rear tires ASAP.. I was looking on TireRack and I was going to buy Goodyear Eagle F1 GS-D3 275x30x19 but they are backordered and you can't get them ANYWHERE :/
So my questions are:
1. If on my front wheels I have 245x35x19 what size should I install on my rear rims? 275x35x19 or 275x30x19? (currently x30x are installed)
2. Which tires would you recommend? (max performance summer - price up to 330...)
3. I just installed brembo from stock g35 manual.. what size of spacers would I need to be able to install stock/standard wheels from g35 04?
4. What would you use to clean burned black brake dust on your rims? I was trying everything what i could find at home and still couldnt clean it :/
5. Which brake pads for brembo would you recommend which would be quiet and wouldn't make my rims black from brake dust in a week..?

OK that's it
Thank You!
Mike
