Well that throws a proverbial spanner in the works. A 210mm M-07 would probably be worth holding out for. Though since it'll be available whenever, it'd mean missing out on a couple of races at least (well, then again that is not to say I'd necessarily have an M-05-based car ready in time for those either due to financial stuff)

Your definition of anti-squat is only partially correct, and as such, omits the main benefit of this suspension setting.

Squat is not a product of having the rear wheels being driven. Acceleration plays the big role there. First off, the weight of the car pushes down on the rear suspension at all times (giving static ride height). When the car is accelerating, the CoG (being above the inner hingepin height) pushes the rear suspension down further (squat) in a pendulum motion around the C0G.

The benefit of arranging the inner hingepins in an anti-squat arrangement is to affect weight transfer, both on acceleration and upon deceleration, granted FWD don't get as much of the deceleration effect as 4WD. The movement of the tire patch in relation to the chassis is so minuscule as to be negligible in regards to the effect of changes in wheelbase.

It's actually not a genuine Tamiya version, it's a well done custom modification. Don't hold your breath.

Fake, errr...custom. I figured out where the pictures were taken. Hint, not Tamiya. Also figured out where to cut to achieve this. I still haven't figured out where the giant servo brace came from. It's actually structural and part of what's holding this together.

I'm game if 210 is available, but then again you guys know what kind of chassis I want.

I figured out the servo mount! DT-03, with a couple of little vertical mounts attached.

Ah, I see. Not sure if that's more good news or bad news

I never stated that squat is due to the rear wheels being driven. I said that anti-squat, as accomplished by angling the inner hinge pins, is enabled by the rear wheels being driven. Here are my exact words:

...anti-squat, which is an arrangement of the suspension that uses the forces from the tire patch being pushed forward by the motor when accelerating...

Yes, a FWD car still squats under acceleration. The remainder of your statement is nicely worded.

Default Rush mini tyres

Regarding the Rush brand of mini tyres, they have specific 24/30/36/40 compounds in the range, but does anyone know the compound of their 'carpet' spec ones?

RUSH Mini Tire Carpet 2pcs #RU-0334
RUSH Mini Tire Carpet Hard 2pcs #RU-0338
RUSH Mini Tire Carpet Round Type 2pcs #RU-0339

I race exclusively on carpet, and have tried the 24 and 30 compounds so far, and found the 24s work great on the rear, but I would like to try the carpet versions as well. It would be nice to know what they actually are though...

If you're running stock parts, then get some alloy c hubs. The ones in that kit won't fit stock applications.
