My RFTs are just about done, and I think upgrading to a top-line street tire is in order.

I know for sure I will be going 225/40/18 in the front and 255/35/18 in the rear on the stock 264s, most likely RE11s or Z1 Starspecs, but running a tuned 135 in a 6MT, my #1 pet peeve is the lack of traction in 1st gear. For those tuned 1ers out there, will these high-end tires going slightly wider than stock help with my 1st gear traction woes?

Also, will "authorized" tirerack installers give me a hard time for installing tires that are not OE spec?

It's really the only option aside from going with a limited slip dif. I can't imagine 3rd party installers hastling you over tire selection.

I don't have a tune but I can vouch for the RE-11's. I've had them on my car for about 3,000km and they grip extremely well. I can take corners a lot harder and my launches are consistently clean. In the wet they are good enough so I'm very satisfied although I may consider a cheaper alternative when I run through both of my sets

In answering your question, running a wider tyre will help marginally, but the biggest difference in going from RFT to a conventional performance tyre. Also, members that have the LSD have only said good things about how much it helps with putting the power down.

Pretty much the only thing you can do is get the widest, stickiest tires you can get, at least without a lot of other work. I'll probably be going with some PS2s come spring time in the same size as the OP wants.
