Adjustable rear upper control arms from Flyin' Miata
#21
You dont really want to adjust the front camber with the FUCA, not enough room in the top of the tire area. Theres a good chunk of weight to be taken out of there though. Just extending the FLCA ~10-15mm is more than enough help in the front of the car for camber. I've pretty much covered all the good ideas that no one else is doing with my arm designs. I've been too busy to actually make a set though. If Keith wants to give em a go though... All thats left is some fixture design.
For the front uppers, 2.5mm of movement of the upper ball joint is worth about a degree of camber according to our calculations.

I'm really not very excited about different lower control arms. But if you've got some drawings to share, it might be interesting to see how you've dealt with the challenges.

there is already negative room between the shock top area and a tire to move the top of the tire further in with even 245/40's mounted on 10" wheels with effective 20mm offset wheels and Im stuffing 275's on 11" wheels in there.
It's the front lowers that need to be lengthened and I need adjustability to get around 4 degrees of front camber.

I've been pretty happy with ~3.8 to 4 degrees up front. 2.2 -2.4 in the rear for high hp off corners and for just straight line grip. The top of the tire inboard clearance issue even gets worse with more camber but the car kept being faster with more. I have the front shocks leaned over a bit more than stock by offsetting the bolt locations in the shock tops Also need 2.25" Id springs instead of 2.5" and I still rub the paint off the springs with the tire after a while.

It's one of those things that would be tough for FM or other vendors to offer as a service. Kinda like welding on the reinforced sway bar tabs.

Space in the wheel well is tight enough, even without moving the top of the tire in..
Bundy, you may talk to Danny George (On Facebook if you have it), he`s a drifter but he`s done a couple interesting thing with the front suspension.
All the FormulaD cars seems to require a very wide front track, and IIRC (could be wrong) Danny made front LCAs and UCAs to widen the track.
You can see how wide it is here;
As far as my understanding goes, they do this for steering angle clearance and to loosen the rear end, but it may hold some interesting info.

Keith how about making a custom offset lower ball joint? It does not have to move out much (1/4"- 3/8") to gain the extra camber everyone wants. It does not look difficult to achieve. I assume you could just contact a major suspension parts manufacturer and just change the spec a bit.
I bet there would be a broad appeal. Not having to press in bushings is a bonus. Not losing inner tire clearance is another plus.

Having said that I don't believe they are as strong as stock and they are slightly heavier than stock. I cracked my first pair within a year and they were replaced. I believe the replacement set has a much thicker wall tube in the tube that cracked.
