Looking to see how many nutcases there are out there besides me.

I feel like 3-4 people in this poll could be lying, or we have the entire population of MTnet that runs 15x10s answering the thread.

I have two sets of 10's and two sets of 9's. fully switching to 10" for track and autocross 245 and 275 widths. I still need 9's for Hoosier H20 wets in 225. but if sombody makes a 245 streetable tire Id get another set of 10's and just have one set of 9".

She told me that my 8" was big enough.

We have 2 sets of 10s. 1 set of 9s, 1 set of 8s , 1 set of 7s. I voted 10s.

Is it even cooler if you have a set of 13x10s and 15x10s?

I need another set of 15x10s but funds are just too tight this year. New motor and paint jobs really make the racing budget go POOF.

Plasti dip is a whole heck of a lot cheaper than paint, like $150 to do a miata with a glossy finish. Its lighter than paint too.

And touch up is simple!

What sort of work do you have to do to make 15x10s fit on an NA?

For the 15x9s with 225s I was able to just roll the fenders and pull the fender liners, but I still can't turn full lock without rubbing against the springs (doesn't really matter except in a parking lot).

15x10 with what tires? 275 hoosiers? A whole bunch of cutting and some front bump stop adjustment. I dont know about the other sizes.

If I was going to 10s I'd want to run 275s. Sounds like it is more trouble than it is worth unless I built a national level SSM car and trailered it.

FrankL

I'm not convinced 275s are the way to go for a national level SSM car. Just not sure it is enough rear tire.

Leafy

Or a national level CSP car.



I think its plenty of tire. The 315 is not worth the extra weight and monster truck ride height just to be able to put down more power. Honestly at 250hp I dont have enough power to break the tires free with a fresh set in 2nd most cases. Now if you took the rear wing off I'd be telling you about all the crazy drifitng. Or if you put 3 year old R6s with no grooves left on the back I'll also tell you about have touchy they throttle is. Now I also don't think you really need more than 250hp to get it done, my car took 2nd in pax a few weekends ago with a top level driver behind the wheel, only the original alien, Daddio out paxed him. And the consensus was that he'd be shaving a second off the run if the car had power steering, or at least a faster ratio rack. And the that day were we hitting the 8500 rpm rev limiter (5 spd, 4:10), which is a higher top speed than the Panda was reporting on the same course. Also had the fastest raw time of a non-formula car by 1.2 seconds. The car is stupid fast, I suck at driving.

Daddio out paxed your SSM car in a B-Mod car? Or was this in SS?

Leafy

iTrader: (1)

In Jim Gary's B-mod, which has top paxed in the region with Will driving so its not like its not normally pax competitive. But whats bigger than that is putting 1.2 seconds RAW on PJ in the Panda on like a 60ish second course. But with my hack *** driving I was still 2.5 seconds off PJ and Dave. I just need to do more to catch them, lol.

FrankL

I don't know about 315s either in 17/18s. I wish we had a short 15" 315-335 width tire. You are saying you can run with Carter with 250hp?

Leafy

iTrader: (1)

I'm saying my car can, with an alien/near alien. And I still dont think an inch more on the tire width isnt worth making the car 2 inches wider and 200 pounds heavier. I think even in a tire height that works for us it wont make the car faster, it might even make it slower. Our advantage over the RX7 is a few inches in width and length and a few hundred pounds.

FrankL

I'd put 315s on but there is no real penalty for us except width. The 10" wheel wideneded the back of the car enough to facilitate flares. We got 10s on the front without them

bbundy

275/35/15 A6 for autocross. however after running 245/40/15 Hoosiers to fit in NASA TT2 Time trials within the tire-weight/hp rules and feeling how good that was in setting down several lap records on several different tracks I feel the 275 tires really would work better on an 11” wheel. The 245’s fit much better on the 10” wheels than do 275’s.

FrankL

Have definitely had those dirty thoughts too.
