I have a couple of questions that my searches cannot answer.
-On our cars what combinations can one run with 15x10 or 11 inch wheels with slicks. In other words what size slicks min-max?
-To run the max slick on a 15x11 wheel or even 15x10 what are your options to make it fit nice in the wheel well besides rolling the lip.
-And finally what are the steps/what is envolved in tubing the wheel wells.

sorry for the novice like questions but my searches were coming up empty and I do not know to much about the subject and plan to run slicks on 15x10/11 wheels.

btw I have a 4th gen rear if that is a factor in any of this which I don't think it is. I am pretty sure it just goes by the offset of the wheels you choose.

thanks in advance

 

Anyone have any input? I know there are people out there running wide slicks on our cars-anybody on these forums?
-Or can anyone point me to somewhere/someone else i can ask?

 

well i know with a stock rear a 15x10 fits with 5.5" of backspacing usually with a 295/50-15 tire. since your running a fourth gen rear you would need even more backspacing to stop them from sticking out.

 

Thanks alot conlinj, now when i wake up maybe ill figure out the conversion to inches for slicks, but my question still remains...
WHEEL TUBS- anybody? I want all the info I can get on them...
-Thanks alot

 

The thing about 15x10 (or wider) wheels is that they kinda stick out past the fender lip ...Looks real ugly IMO. I run a 15x8 wheel with 5.5" backspacing and the biggest tire I've fit to date is a 28x10.50 ET drag. I had to beat in the front portion of the wheelwell because it rubbed a little ...nothing that a hammer couldnt fix. I now run a 27x10.50 QTP on the same tire and they're obviously consideribly smaller ...they have so much room to spare its not even funny.

 

what tires stick better for ya? the et drag's or the qtp?

 

-id like to know that too.
-and i know with a 10" or bigger rim the tire will stick out which i don't like either, hense my questions about tubing the wells and shortening the axels/getting rims with lots of backspacing/ I don't know to much about how to do it and what parts to cut out and where to weld in the tubes themselves. If anyone has anything to add please chime in.

 

well depending on teh motor your running are you going to need that much rim and tire? I'm running 15x8 with 4.75" backspacing and a 28x11.5 ET Street. What suspension mods do you plan on. I'd be more concerned with that.

 

In simple terms, I am not up to the motor yet. I would like to start building it up/ still don't know -either 383 stroker or blown 350- but as for as now my new 85 iroc is striped down so I was planning on putting a cage, trick/drag springs, drag shocks, lca's, lca relo brackets, panhard bar, 4th gen rear, sfc and some other goodies that are easier to put in without an engine, tranny or interior in the way.
I some day want to see single digits on the bottle if I dare and figured now would be as good of time as any to shorten the axels of my new rear /while its laying around/ and cut and weld new wheel wells. I know 10" / 11" wheel will be overkill and hurt my tranny and rear but I think it is the better decision when I look into the furture...and anyways I love the look of big fat slicks.
So with that aside does anybody have any pics/ articles about actually tubing the wheel wells? -I'd appretiate if you would just forget about whether or not I need that size slick and guide me to some answers/by all means give me your opinion but give me some useful info with it>

Thanks

 

if you don't have the lca relocation brackets don't bother getting them, heard their not worth a thing, unless ur car is lowered. But you car will actually sit a little bit higher with those drap srpings, I have the Eibach Drag Launch ones. We have cars running into the low 7's with a 10.5 inch tire so it may not be worth tubbing but it's your car and your look, ahve to respect that

Thanks for your advice Jim, 10.5" slick is on an 8" wheel? Is that safe? what is min-max-recommended?

 

yeah a 28x11.5 et street only has a tread width of 8 inches. A true 10.5 inch tire will require some massaging tho

-Jim

 

im running 26x10x15 dot slicks on weld prostars 15x10's with 5.5 bs and there not past the fender lip just yet. if i had a 10.5'' wide tire then they would but its just about even.

 

wow a 15.3 with all that? and a 2.2 60' with slicks? you got something wrong? I ran a 15.2 with a beat to hell 305 tpi peanut cam'd motor. Also a 2.01 60' on street tires. I'm not attacking you but i'd figure you'd be faster then that

 

Im in the middle of Mini Tubbing mine now.

I used a plasma cutter to remove the inner wells and bumpstop that sticks out preventing a wheel that sticks in more.

This is a 27x11.5x15 QTP

You can see I could prob go a little bigger because this 11.5 tucks under the lip. Stock Plastics will remain on the int.

I'm actually shooting to stuff a 17x11 or 18 under it with a 315 BFG DR

 

What size rim and backspacing? for the qtp?

 

that 15.3 was on street tires. i havent ran the slicks in about a yr an even then i still only pulled a 15.6 i think. i think with the slicks and how damn stiff my suspention is it was just killin my 60' times and 1/4 times. since i ran the slicks ive done 3.73 gears, edelbrock rpm air-gap intake, relocated the battery and i think thats it. im goin to try them one last time this comming weekend for slp day. im goin to run once and if they dont help then ill go back to my street tires. just tryin to get the 60's down and see if i can run faster.

i might go with either a 9.0 or 8.0 wide slick when i get new ones, maybe the 10'' slicks are slowin me down a bit

 

They are 15x8 no clue on the BS Im borrowing them from a buddy who runs them on his 406 S10.
