3.14 You may alter the car in any way called out in the “car instruction manual”, or “chassis setting sheet”. If the “chassis setting sheet” calls out the adjustment, then it’s legal to make the change to your car.
most bodys have dimples you can use for body post on the bumper. And if using a tamiya part u can obviously tell its not a modification because there is a provision on the front bumper for them.

Same, so if its legal to build outside of how the manual states then this would also be legal.

What rule did they cite as to why one is legal and the other is not? Its should be in black and white what are considered hop ups and what are not.

the rear of the car was not designed with those parts being used in the rear but the front bumper was designed with the front body post in mind. That's why many bodys have dimples in the bodys already for the foward most body mou t

Again the kit has pre drilled locations for 90° body posts. The posts are sold in a parts package.

The stock kit has 0° rear toe. The hop up parts give you 2.0° and 2.5°

These parts are not sold in a hop up package. These are parts put together ad hoc to create ARS. This is adding variable degrees of rear toe control and active rear toe.

Thank you to those checking directly with Tamiya, as I am very excited to find out the official decision. I've been wanting this, probably like many others, so that any body I mount on my GT Pro Spec car I can also use on my GT2 chassis (TA07) and vice versa. Unfortunately, I've already drilled two new bodies for existing TT02 front body posts, but if for future bodies I can start using those bumper mounted posts, I'll be ecstatic!

These parts are TT-02 specific parts and part numbers where as the body posts are not. You are also not drilling any new holes for the ARS mod either.

I wonder if its purely based on the chassis having intentional accommodations for bumper mounted body posts, versus someone's clever idea (ARS) that Tamiya hadn't considered. I agree with you on the rules part, as I read it the same way you did that the kit needed to be built according to the manual. Sure it doesn't account for all hop-ups, but every hop up replaces an existing part in the same location, where the body post is different. I'm looking forward to the official answer!

Hello Larry,

The short answer is yes. You may mount the post on the bumper or the shock tower. The manual to most TT-02 spec cars show this as an option.

Hope all is well with you.

Hopefully we get the same answer LOL! I did go back and look and skipped over this the first time

3.3 Any Tamiya Hop-Up Option and spare part is allowed, if it’s used in the way it was designed and installed on the vehicle it was designed for.

Edit: Thats unfortunate that is his official answer as there are no TT-02 manuals (unless I missed it in the base model, R, RR, or SRX manual) or part number that show that as an option.

Its very washed out on Tamiya's site so I didn't catch that.... but I did catch this

15.1 Legal chassis platform: TT-02, TT-02R, TT-02RR kits only. Note: TT-02 Type S kits are not legal for this class, nor TT-02 Type S specific Hop-Ups. Any TT-02 Hop-Up Option is allowed with the 2 exceptions listed in RED: No aluminum shocks. No carbon shock towers.
