Im hunting for abit of advice, have my r34 gtt and it needs some new shoes. Im looking at a set of jdm concepts and works joint venture the gt5's. The sizes are 18x9 +30 for the front and 18x10 +38 for the rears. Ideally 245's on the front and 265's on the rear. Ive got what looks like stock height if anything maybe slightly lowered. Based on experiences what problems could i encounter and any ways of getting around them?

Merry Christmas all, Santa has brought me a fuel leak as a present which I am extremely happy about. It started yesterday when i filled my r34 gtt right up with e85, went in to pay and came out to find the fuel I had just put in was coming out onto the ground. After 5 minutes of solid leaking it stopped, so i started the car and it started leaking again not as bad though. Finally when racq came i started it and it wasn't leaking and then drove it the 5min drive home. Old mate from racq said it was my fuel pump seal but he also told me that my inspection cap for it was under my rear seat so I don't really trust him. My question is does anyone know if this is actually the case or whether there is a point half way down the tank with a seal that could have gone? Cheers
