03 Cobra Recommended Slick Size

etony89 · April 22nd, 2008, 01:59 AM

What size rim would fit on my 03 cobra. It has irs and stock back brakes. I would like to go with a 15". I know where I can get some slicks that are 27x10x15. Would some 15x8 rims work on that or would I have to go like 15x9 or 15x10. I am looking at purchasing in the next couple days. Also what size backspacing should I get? I want to do this without modding the brakes. Thanks

will 15's clear the breaks? i know they wont in the front i think 17 is the min up front...
sorry i know nothing about tire size...
are you lowered? if so how much?

etony89 · April 22nd, 2008, 10:45 PM

I am just looking for in the back. I am not going to be doing anything with the front tires. It is my daily driver so it would just be something to put on there when I race it. It is lowered on eibach springs. I am not sure how much but probably like 1.5 or so.

Yea it will clear.

etony89 · April 23rd, 2008, 09:24 PM

ok so the 15s will clear without modding it. what size backspacing should i get? or what will look/work best? and would the 15x8s work on the 10 inch tire?

You have to do some grinding on the rear to get 15's to fit....if you're stil IRS of course.

15x10 6.5in BS Weld ProStar needs grindin

etony89 · April 25th, 2008, 07:47 PM

well what will without grinding.

If you have stock cobra brakes any 15" rear wheel will require grinding. The wider you go, the more grinding it'll require. I ran 15x10's and had to grind the banjo bolt, tie rod end and the spindle where the tie rod mounts. There are several wheels made to clear the brakes. Bogart makes a 16x10 and diamond racing makes some more budget minded 16's to clear.

etony89 · May 6th, 2008, 01:20 AM

do you know where to get some like 26 or 28 x 10.5 x 16 slicks. i would most likely wan some dot approved slicks to run but if i can't find some then straight slicks would work too. i got some rims that i can put them on i just need to find somewhere that sells the tires.

Summit, Jegs or Wells performance out of Florida. MT makes a ET street in the size you need and I believe Hoosier makes the quick time pro(equivalent to et street) in that size as well.

wheels 8-15-5.5 back spacing......slicks 27-11.50-15s

etony89 · May 6th, 2008, 06:44 PM

so the 11.5 inch tires would fit on the 8 inch rims? just making sure so i dont mess up on them and have to wait longer. and thanks for all the help.

futureMACH1racer · May 8th, 2008, 08:11 PM

I wouldn't go any wider than 10" unless you have some serious power. To much traction can be a bad thing. Also, watch out for wheel well clearance. 10" wide wheels with a +22mm offset, and 295, or 11" rears with hit the quaters if the car squats hard. My car trnafers really well and slams the ass end down, I had to roll my quarters because I caught while launching.

etony89 · May 9th, 2008, 09:38 PM

well i am hoping to be right around 500 to the wheels. i will probably just end up going with the 10.5 slicks or maybe even 11.
