Bogart might build a set but they are going to be about $500 ea, not to mention when I discussed 11" wheels with him before I got any 10" wheels Rich didn't act like I needed anything bigger than 10" wheels. I have never dealt with the others but assume probably similar costs. I don't care enough about the 949 wheel to consider it "screwing it up". I am trying to build a BSP national champion car, not a show piece. Then there is the whole "I already have 2 sets" of 949 wheels, so that $800 is already spent.

It'd be a lot cheaper to get some 15" steelies from the junkyard and have them widened. Yes, big heavy steel wheels, but at $25 per wheel versus $210 each for the 6ul's.... Not to mention it's easier and cheaper to weld steel.

I don't want heavy wheels. I'm spending lots of money finding 2-3 pounds here and there to get weight off the car. That makes zero sense for me.

Sorry. Didn't realize that money is no object.

The "feeling" of snap break away is gone, but the chances of snap break away aren't. Drifters run the same tires because it's easy to snap break away compared to proper width tires. The feeling is your tires loading the sidewalls while turning, then unloading when you jerk the wheel, or aren't smooth with gas and brake. I'd much rather get the feeling and know I did wrong, than to have it just happen with little warning (other than tire squeal). I don't see how removing one of the warnings would make them easier to drive for a novice. We got pretty familiar with that feeling in the Mustangs, 8" wide wheel with 245's. The whole point of the track time was to smooth out our inputs to avoid upsetting the car.

If you want a better contact patch, buy good tires. For example, Michelin and BFG both have technologies designed to increase the area of the contact patch as more force is transmitted to the outside edge of the tire. Michelin calls it Variable Contact Patch 2.0, and BFG calls it Enhanced ETEC with Dynamic Suspension.

You're picking an oranges comparison for our apples. Those 275's have more sidewall to move, so will definitely have more squirm in the exact same situation on a 10" wheel. The 245's are better for that wheel. This can be helped with proper pressure, although an 11" wide wheel would be better.

225's on a 9" wheel are not significantly stretched. 185's or 195's I beleieve is too far not 225.

Nobody said money was no object I am just not interested in putting 20lb wheels on my build.

I feel like you may have wandered in to the wrong thread...

Latest issue of Grassroots motorsports. testing a bunch of 225/45's on a civic. They couldn't fit 9" on the back but when they switched from 8 to 9 just on the front the went a half second faster. Both With G force rivals and RS3's. The tire was better in every phase of the corner they said and lap times were more consistent with an easier to drive at limit. But I already knew that. done the test myself, Even did the 9 front 8 rear combo on my all wheel drive 323 GTX.

FWIW the 275 and 245 Hoosiers have exactly the same sidewall and diameter. looks like they just change out a center ring in the mold to make the two sizes.

z31maniac 10-31-2013 10:18 PM

Yep, they just add a spacer to the middle of the mold.

Yes, I run 225s on 9s and they are not stretched, especially not Hoosier A6 225s.

Mmn710 12-28-2013 01:19 AM

I run spec miata so it's 7 for me lol but if I were to build a fun street/track miata. Not gonna lie but I'd go with 9s since they look so aggressive.

guttedmiata 12-29-2013 04:58 PM

The poll doesn't even give me the option to choose my 12s.:p

mrvwcastner 01-19-2014 02:01 AM

I've got 8 9" 6uls & 4 10" I need to go all 8" 9" now for exocet. Anyone wanna swap 4 blk 10s for 8s? I would like 6 8s for 4 10s 2 have never been mounted, or 4 for 4 you pay shipping. I love my 9" front 205 50s 10" rears 225 50s with flares.

Where are you located? I maybe interested in buying the 10's outright.

mrvwcastner 01-19-2014 11:58 AM

I'm in Portland OR. Email is mrvwcastner@yahoo.com

I really need 10 8" & 2 9" to complete what I need for Exocet project to run staggerd 8"/9" 205 front 225 rear. I guess I'm waiting for Emilio to move production to the US.

Kramer 02-17-2014 07:33 AM

I'm currently running 15X8 +10 and the handling is pretty good. 9inch wheels seems to be too agressive for me, but everyone knows that their style is superb. Not knowing if they are good in the track, surely Miata.net users wouldn't agree with that.

mrvwcastner 03-08-2014 08:57 PM

I sold my 10s I guess my vote is null & void now. 2 sets of 9s with 245s &I need to sets of 8s for the 205s I have. This is all on Exocet with 1.6. Big motor next year.
