RPM Starz,Typhoonz,Torkerz Question

Does anyone here run these wheels? I'm looking for the off-set measurement on Losi rears and Associated fronts. I'd like to try a set on my B4 EDM, but don't want the front track to be wider than the rear. Thanks in advance.

All Losi truck wheels are 7/8" backspace(from edge of inside rim to mounting surface)
All AE truck wheels are 5/8" back space
The RPM wheels are the same dimensions as the stock ones.
Losi XXX and AE B4 rear wheels are 7/8" backspace-they are interchangeable but it is hard to get a Losi wheel nut on a B4 wheel.
AE B2/B3 rear wheels are 7/16" backspace
AE B4 front wheels are 15/32" backspace & 1" wide
AE B2/B3 wide front wheels are 5/16" backspace & 1" wide

Having the front a little wider than the rear is better than having the rear wider than the front but it is best if they are pretty close to the same.

Excellent information! Thank you

Maybe you can help me with a few more questions.

Do both the AE and Losi trucks use a 3/16" rear axle?

Will a T3/T4 front wheel bolt directly onto a B4? Or do I need to buy T4 fron axles to mount on the B4?



I'm trying to figure all of this out without actually having anything physically in front of me. The B4 kit is on it's way here from Hawaii. I'd like to pick up the wheels/tires and whatever else I need to make this work so I have everything when the buggy arrives.

So, if my calculations are correct:
A B4 has a front track width of 9.75". The rear track width is 10". If I use the RPM AE wheels for the front, and the RPM TL wheels for the rear, the front and rear track should be EQUAL.(?)

They both use a 3/16" rear axle(except for really old AE).I don't have a B4 here in front of me either but I am pretty sure you will have to put the T4 axles in the front-the buggy ones are probably too short because the bearings are spaced farther apart in truck wheels.

In theory Losi fronts and AE rears should make it 11-1/2" wide in the front and 11-1/8" wide in the rear which would be fine-prob be a little different when you get it all in front of you.You may also have to put truck steering knuckles on it to clear the wheels-I don't know if B4/T4 use the same ones like B3/T3 do.Good luck!

The b4 and the t4 use the same knuckles just on the t4 the axle is longer.
