I bought these, and then decided to sell my 03 Cobra (with the original wheels/tires.) These wheels are in new condition, tires less than 2k freeway miles, no burnouts or abuse. These look outstanding on a mustang. Tires are Toyo T1R. Very nice tires. Front wheels are 18X9.5 with 275/35ZR18...

I seem to be accumulating more brake dust in the rear wheels than in front. I have 7k miles on the car, no racing, just an occasional burst to the limit in 2d and 3rd :lol: , but other than that pretty "normal" miles. Is this right? I used to get significantly more dust up front in my 99...

Today I installed the predator performace tune, and made some adjustments to the fuel base. I achieved a fairly flat A/F at 11.9. and got good increases in HP and TQ up the whole RPM band. My question relates to the "Max" increases and today's temp. My previous run on the dyno (it has been...

Please explain the proper a/f ratio for the 03 cobra, including why?

Sorry if this is a tired subject, but without a search feature this is necessary. I'd like to use a flash tuner that can return to stock, but not too sure on which is the best way to go. Maybe there is another brand that's better... I'll probably stop with the performance mods after this one...

Took my car in to the dealer to get rid of the squealing (I belive caused by the stock belt/pully system). They put some "goo" on it, and it went away for 15 minutes. Waiting for a new belt and idler to arrive for installation. I hope this fixes it. I hate the sounds my muscle car is making...

Could one of you guys please explain the A/F ratio? Doe this number (for example 10:1) mean 10 parts air, one part fuel? Once that is clear, can you also explain what ratio is optimum, and at what levels leaness could be destructive? One more question, with the mods I've made, and my...

I'm wondering why the Cobra IRS has such a problem with wheel hop... The Corvette doesn't have this reputation, so why hasn't Ford figured this out? Can someone explain this? I'm on my second Cobra with IRS. I had heard the problem had been worked by Ford (since the 99 model), but after...

Hi to all. Can anyone explain to me how to remove the plastic inserts inthe side scoops?
