I have ground clearance issues with the low engine mounting. Running low ride heights in the front, lower than 4.5", leaves me less than 2" of ground clearance to the k-member and the oil pan. At 4" I would have less than 1.5" of travel which is not enough even with 750# springs.
Agreed on the preference for moving the lower end of the knuckle outward, rather than the top of the knuckle inward. |

Full lock clearance with a 15x10 is a pipe dream. I would expect it to rub half a dozen things at full lock - the front bumper, the FSB, the UCA, your mom's tits, etc. We're looking for shock tower and fender clearance - the shock tower is very tight with the 10s. If I can compress to the bump stop and sweep the steering wheel 270* in either direction, then in my book it fits. Have you checked things with the 245 installed on the 10? |

The 10's only go in 2mm further than the 9's. I was hoping all of the clearance issues would be limited to the fender side of things.
Have you checked things with the 245 installed on the 10? It's really hard to get good photos in our shop, so this is all I have for now. There's just no way to fit them in the front, and I've got the rear just about cleared on one side but it took a huge amount of work and looks like crap, so I ordered Autokonexion over-fenders today that add 30mm of clearance on all 4 corners. Hopefully that's enough to avoid rubbing at full bump. They are pretty god damn sexy, though. https://www.miataturbo.net/attachmen...ine=1321317994 |
Thanks for the pic Sav.
If you get a chance can you test them on your '99 rental? I have the wheels on the way, but no tires yet. Curious how fitment will be on the NBs. |

I think the Autokonextion kit will be the perfect match for the 10's. I sold both sets of my 9's and will replace with 10's. |

We just installed some 900lb springs and set the ride height at 4" in a friends LS1 Miata. I don't remember the oil pan clearance though.

So how did you get in touch with Autokonexion? I sent them an e-mail and called them twice. |

my bad, confused trackspeed and 949racing's rentals.
Well I guess I'll have to see how much more I can roll my fenders. |

I have been seriously considering going to 900 lb springs. Dean Thomas (DTfastbear on m.n) is running 900/550 on his LS1 Miata and tried them with these tires. He was pretty pleased.

Welcome to my world. :) I think the Autokonextion kit will be the perfect match for the 10's. I sold both sets of my 9's and will replace with 10's. |

LOL that's who I was referring to. Those were my tires we tried.

don't forget, cali tracks not = to Tx. tracks for the most part. we have alot more bumpy tracks. (and are bumpier too!, lol)

They are pretty god damn sexy, though. The rears are a different story. Multiple layers of metal = you pretty much have to do a add-on flare. I've got the same Autokonexion rear flares (the small ones) as you ordered. -Ryan |

Ah, blister fenders. I misread. I was going by memory that the rear flare I have adds ~30mm, and skimmed over that detail. Disregard then. The main benefit I saw to cutting the OEM fender and flaring it out was that it was better in terms of front aero than a add-on flare, but the blister fender accomplishes the same thing. Just costs a lot more than a cutting disc for the dremel ;)

don't forget, cali tracks not = to Tx. tracks for the most part. we have alot more bumpy tracks. (and are bumpier too!, lol) So the tire engineer at Hoosier told me that -2 degs of camber is enough for this tire. Maybe he just wants me to cord the outside edge prematurely so they can sell me more tires :giggle: At any rate I'll take the emperical data presented here and start with increased camber, say at or more than -3.0 degs for starters, with careful tire temperature measurements. |
LOL, I meant we have more bumpy tracks, and more of them! But yeah, i for one am alot "bumpier" than those camel jockey's!
