If I am doing some tuning at the track/autocross it isn't very easy to undo one bolt of a control arm or toe link and adjust it then put it back together. It really needs a RH and LH thread so it can be done on the car.

This. If everything is adjustable without having to be unbolted from the car, then I would be in for the full rear package.

The toe link is adjustable on the car. You undo the two end nuts and turn the turnbuckle in the middle which should lengthen or shorten the arm, then tighten the two end nuts after adjustment is done.

Nice work, dudes! Can't wait to see the group buy go up.

Yes, they are fully adjustable on the vehicle. It does use a LH/RH thread.

Ask and you shall receive. We are updating the lower rear control arms to offer that. Hopefully should have some pics of it soon.

just placed an order with race x fab. hands down best customer service i've seen yet. do your research, these guys make a quality product vs many off the shelf parts out there. they'll answer every question you have and can make custom bits/tweaks to your liking.

the after sale support alone is worth it

i looked into other LCA and considered GT Spec/Whiteline/Stance/Cusco/SPC/Agency Power/Race Fab (the NZ company, not race x fab)/Hancha

in the end I chose this as I felt it had an overall advantage as a package vs the above products.

-ease of adjustment (no subframe getting in the way)
-its strength using 4130 chromoly body and teflon lined steel rod ends (comes with dust boots for the street wary too). this factor is extremely important to me as i've experienced control arms (albeit stock) bend from spinning out and running sideways into a ripple strip.
-no poly flex since using rod ends (can also be easily sourced and replaced if needed)
-3.7 lb vs 2.2lb stock. good weight compromise considering materials used
-very good pricing and after sale support

I need to find some money....

Jeff@Racer X Fab · 03-26-2013, 10:14 AM

We have the rear upper control arms tacked together, and will be fitting them in the next few days. Very happy with the results, as usually for all of our suspension parts full 4130 chromoly. Adjustability at the hub, and bracing added to increase the structural integrity. This part allowed us a nice weight savings of 4 lbs per arm!! This is of course due to the OEM part being made from cast.

We will be offering all of our suspension parts with a urethane bushing option for those that are interested.

Those UCA's look sweet, I'd much rather have adjustable uppers than lowers. These won't be adjustable on the car by chance, will they?

solidONE · 03-27-2013, 04:22 AM

What gauge material and tubing diameter are you using on the arms? Love the gusseting!

I'm sure that it would be possible to make these on car adjustable, I will take a look at the hardware we will be using with the updated rear lower control arms to see.

We use 4130 chromoly 11ga (1/8th wall) tubing and sheet stock. All of our control arms use the same. We chose this material, and thickness from our past experience in racing with the MR2. Our suspension parts are designed to be durable and last for several racing seasons or harsh street use.

1" tubes? Or thicker?

1.25" diameter, this includes the front lower control arm and rear lower control arm.

Awesome! I just spent $1,500 on track fees, $1,500 on wheels and tires, $400ish on various brake bits, need some ducts now.. ugh.. the rear UCAs will be ordered when car cash flow is available!

Jeff@Racer X Fab · 04-01-2013, 09:07 AM

We had some time to test fit the upper rear control arms over the weekend. Here are a few pics of how we made the conection to the OEM hub. We will be adding weld nuts to the rear upper control arms to retain the harness plate that is used by the OEM upper control arm.

We also had a chance to install our updated rear lower control arm that is fully adjustable on the vehicle. No clearance issues with adjusting the arm, extremely easy to access the adjustment point and not hidden in the cross member.

We are now gearing up to have stock of all suspension parts that we make, and will be offering an initial discounted rate for all pieces.
