RideTech Spindles Question

[Smoker03]

Great info Bret and I would say it is spot on. I am running your spindles with z28 arms now till I have the budget for the rest of the true turn system. I have a 17x8 up front with 4.5" of backspacing and I wouldnt push it past that with the stock steering arm. The spindles are a very nice piece and I look forward to getting the rest of the system on the car. I am running GW upper and lower arms with zero BJ bind. I was also able to get 6 degrees of caster with no issues.

With this combination the diameter of the wheel is not an issue because the steering arm won't fit inside the bell of the wheel anyhow.

IF you use the complete Tru Turn system [which includes the RideTech spindle and the RideTech steering arm along with the rest of the system] you can use up to a 10" wide wheel with up to a 5.75 backspace...IF you an 18" diameter wheel...OR a 17" billet wheel. MOST cast 17" wheels do not have enough inside diameter to clear the Tru Turn steering arm. I say most becasue we have not tried every wheel made yet. So far, in a 17" wheel diameter, the billet wheels we have tried have cleared fine, the cast wheels have not. Clearance is not an issue with an 18" wheel, billet or cast.

Having said all that I am quite sure that someone somewhere makes a 17" billet wheel that will not fit, and a 17" cast wheel that will

If you are going to use another brand of control arm, or an oem control arm, just be sure the run the suspension through its travel to check for ball joint bind and any other clearance issues.

The RideTech spindle does NOT move the wheel mount hub out any, BUT some brake kits do that. Ask your brake manufacturer. From experience I know the Baer systems duplicate the mount position of the factory DISC brake system, but be aware that the oem disc brake hub [and the Baer hub] is about 1" wider than the oem drum system. [That little tidbit cost me a set of billet wheels]

I just bought your spindles and haven't put them on yet. Are you saying that there is a loss in backspace running your spindle without the the rest of Tru turn system or is it a wash between spindles and stock steering arms? I was expecting to be able to run 5" backspace.

The max backspace you could run with stock steering arms is 4.5". I'll get you some pics. If you run the tru turn system you should be fine going with that much backspacing.

The key player for backspace clearance is the Tru Turn steering arm. Without it, 4.5" is about the max backspace. WITH the rest of the Tru Turn system...up to 5.75 on a 18x10" wheel.

Just to reiterate what Bret has stated. Here are the ridetech spindles with stock z28 short arms and a 17x8 with 4.5" of backspacing.
