Looks like either 22 or 24 mm rotors would work just fine with my Outlaw calipers. I was leaning towards Speedway's scalloped .81" two piece rotors as they are very light but now I wonder if someone might not be making those in a 22 or 24 mm thickness. It'd be worth paying a bit more for them if so as long as it isn't an extravagant amount. Still have some front end work to finalize before I'll know for sure what offset I want for the hats but I suppose in a worst case scenario I could turn and mill a set myself if I had to.

I talked to a guy at coleman today, and their aluminum hats are around 70ish, and a custom made rotor for their hats are about 80ish.

"I plan on using 86-87 Acura Legend front sedan rotor,10.4" diameter and 20mm thick vented like the RX7 for the rear kit. Perfect match. You could just drill your hub pattern between the 4 existing holes for the front and drill your wheel pattern between the 4 holes in the rear and slip on. Not knowing the hub diameter or axle diameter of your Alpine, may or may not have to be turned down to fit. You can get fancy slotted and drilled rotors also."

I was looking on rockauto and it loks like the Acura rotors are 21mm, while the RX7 rear rotors are 20mm. The mid 90s Miata front rotors are 20mm 4 lugs. My local auto parts store had neither in stock so I couldnt put a tape measure on them to see if it would clear my axle flange. If I remember correctly, my axle flange is somewhere in the neighborhood of 6-6.25 inches. Is there any resource that shows the measurement of how large rotors are where they slide over the axle flange?

Robbie, Check the Rockauto site again under Centric. It should show the dimensions. Brembo might also. Or junkyard shopping. A 1/2 mm on each side shouldn't matter. Those 8" Ford hubs might have to be turned down.

Rockauto doesn't show those dimensions. I guess I'll have to go jy shopping soon.

Robbie, Rockauto has hub diameters on some vehicles. Looks like 5-5.5 inches most common. Wilwood lists 2 hats in Sunbeam bolt pattern(same as 79-83 Mustang 4"X4.25"), Check this link out. [www.revolutionbrake.com]

I should have. Went with 16" wheels instead of 15. That's what's causing the problem for me. The hat for the rotor the thickness I need and will fit over my axle flange only has rotors that are too big to fit inside 15" wheels.

Jim N, RX7 upright ? (McPhearson strut). I need a light, strong spindle, for SLA. and tall enough to have low roll center migration, with bolt on steering arms. Jensen Healey seems too weak,(11/16" and 1and1/16") dia's. Suggestions ? Thanks, roverman.

Art, Newer Mustang and Camaro are Mcpherson strut. I thought you were going double A Arm. Some Locost builders cut the strut down and weld a 3/4" bolt on top and use a Heim for upper ball joint. That is probably what the 510 with RX7 lower A arm and Supra upper A Arm did.

Art, It is on a Datsun 510. I thought the article said it was RX7. Maybe It is Z or 510(also strut), If you do a search on Strut conversions to Upper and Lower A Arm on Locosts you might find some pics on the Heim. Or you could use a upper ball joint like this newer Mustang. They cut down the strut and use it as a spindle..

Re: 5-lug Front Hubs? Stronger spindles ?

If I thought I could "trust" the JH spindle @ 1.5 g in 2,400# car, but if not enough, could get messy !" Wilwood, Mustang II, I feel is too heavy, but I want bolt on steering arms. update, considering "like" Mustang II, but has centerbolt at top,for wheel cylinder? Identicle ball joint sizes top/bottom(5/8") large end of tapers. N.O.S., think I can make work. What's that air bag # that works on MGB's ? Thanks, roverman.
