Consolidated Widened Alcoa/Tire Post


A10ACN

Recommended Posts

Could we get a consolidated Alcoa post which describes the positives/negatives and perhaps tire choices for the different widths? For example, if I understand correctly, going to 11" doesn't (shouldn't) require cutting shock covers or bumpstops, does require removing the brake ducts, but limits tire size to 305? Others require spacers, limited tire choices and so forth. If I'm mistaken PLEASE correct. This could be a beneficial sticky for folks trying to determine their options, especially with all the hard earned knowledge on here.

I'll even add Reg's thread that shows a shortened Super Snake axle to pull the tires inward with 305's installed on stock 10" Alcoa's...................

Robert, thanks for putting all those threads together. I was looking more for one thread which had all the width options listed with the pros/cons of each. It could serve as a quick reference and allow folks to comment on what set-up they're running along with any problems or new tire announcements. One thread to do it all.

Someone else will have to sort through that. It will take much research to identify what has been found so far. If one person had tried all of the tire and wheel width options it would be simple, but since they are spread out among so many threads including trial and error fitment, it could take some time to sort through what is known to work, what is known to not work, and then list what has not been tried yet.

Oh, I agree, lots of information and opinions spread across several years. If each person with a particular set-up posted in what I'm talking about and listed their choices and pros/cons, we could have a pretty good compilation of worthwhile info. JMHO and the reason I brought it up.

I agree.^^^^^^^^^^^^

 

One recent event is the fitment of the 12" set up with 335 PS2's on Lee N's car, but an 11.75" set up with 335 PS2's on 03 DSG's car has unacceptable contact issues. It would be nice to know things to look for on the car itself, when a 335 tire is chosen.

 

I think some of the smaller sizes, 11" and 11.25" may have not been explored as much as the larger sizes since many of the 725 guys are trying to get as much rubber as possible under these cars.

That's the kind of info I'm talking about.

This will be difficult because there are alot of variables... but I'll try to do my part:

 

I'll post my info:

 

current setup:

widen rears to 11.75" with Toyo R888 315/30/20. 1/8" spacers on both sides. stock rear brakes. these are almost exactly stock height. I did trim the bumpstop bracket and remove the shock dust boot. 'stock' SS FRPP suspension with CHE LCA relocation brakets and STEEDA LCA's. moved my stock 275's to the front.

 

 

Tried but failed:

tried 335's on these 11.75" wheels but could not get them to fit without rub. could be my inexperience, but i tried for three days to get them to fit and couldn't. if someone can teach me the "trick" to get them to fit i would mount them up in a heartbeat!

Ron, I am ready to move up from the 305's on my 11.75's. I guess to be safe I will go with 315"s instead of the desired 335's. My question is did you have to use the spacers? If so, why?

 

Thnx

I was wondering that also, why 1/8" spacers with 315's?

 

Another question for Ron..........At what point did your 315's make contact? full articulation or before?

 

Thanks, R

i had symmetric rubbing with the 315's when i did not use spacers. panhard was centered dead on. i cant explain why, just know what i saw, felt, and heard.

 

i'll attach pictures of when the rub occurred. basically at full articulation. these pics are of the car going over a standard drainage channel in my neighborhood. when you hit it at an angle, you can see that one side compresses fully and the other extends fully. this is when i got the rub.

 

i'll also attach a shot from the back so you can see that the profile looks stock even with the 1/8 spacers.

Thanks for the pictures.

 

 

So you did all of the mods, shock boot cut or removal, bumpstop bracket removal and seam sealer/sound deadener removal? and even after all of these mods 1/8" was still needed?
