How do I determine what my wheelbase is? Also what motor mounts are compatible with my setup.

PN Racing has some pretty trick mounts but they just have milimeter ranges, so i don't know if it will fit with my Toyota GT86 body. (FRS)

Right now, i have a narrow setup, RM, on the longest H-plate setting (i think). How many millimeters is this, and how can i determine if it will work with a motor mount or not.

The GT86 is a 94mm body. There are guides on the internet that show what wheelbase a body is, but you could even use a ruler to find out - just measure from locknut to locknut.

MINI-ZGUIDE.COM (Comprehensive Bodies Data Base) has a great Comprehensive Bodies Data Base listed by wheelbase.

Thanks for the quick reply, so any 94mm motor mount will fit my body??

Also, what is the offset for the front and rear wheels?

Search much? Short answer, no. High mount will not fit.

Actually the gt86 on there is for an awd version and the offset is definitely different because that's what I followed and was incorrect in the rear.

They have the BRZ on that list, and 1.5N 1.5N should work....iirc the actual offsets were 1.5N and -0.7W, which is basically equivalent.

Got pictures? The fear ends are the same unless you are using an LM rear with an lm diff.

The BRZ is an narrow body. Therefore the front end of your chassis should be set to narrow. The rear is unchanged others than to lengthen or shorten the wheel base. There are two different lengths of T plates, MM and RM. If you use the stock RM mount you will need an RM T plate.

Offsets:
Front: 1.5N (Based on Mini Z Guide) and narrow plates
Rear: 0W (Based on GTR offset because I have a sports model which looks exactly the same as far as wheel offset)

Assuming N means narrow wheel and W means wide wheel.

For the AWD, its probably the same up front, and narrow wheel in the rear instead because the rear width on awd is probably bigger im assuming.

Wheelbase:
94mm (Measured with a caliper)

So what's your question again? Did you buy everything new? If so it should have come with manuals. Thos printed manuals are sometimes more up to date than the electronic versions.

The post from Mania above has it right. The rear needs a negative offset wide wheel (the auto scale lists it at-0.7) so if those are after market wheels (and your BRM mold is correct) then you need to find that wheel look in something close to-0.7 or modify the body carefully with a Dremel to allow for rear suspension movement without contact

the wheels in the picture are the stock wheels that came with the model. Nowhere does it say .7 offset anywhere. I have read all hte documentation for everything that i buy.

there is a stat sheet that comes with all autoscales telling what the wheel size and offisets are.

must have missed it or maybe it wasnt included.

You may have bought a slightly off size body....I have three different Ferrari 458GT2 that all fit the rear offsets differently. One can barely fit +2, one just fits +3 and the other has a big overhang when using +3. It's the nature of the outsourcing of the manufacturing that bodies sometimes aren't the same from one to the other.

If you're handy with tools you can make the wheels work by filing/sanding/dremeling the inside of the rear wheelarch so that when the suspension pivots on its axis the wheels won't rub.
