[Help picking lightest Tamiya chassis with best grip for indoor racing]

Even lighter is a RM-01.  It's 1/12 scale instead of 1/10 scale.  It's around 750 grams full loaded with electronics and battery, or about 60% of a touring car.  Since this is indoor and on a controlled surface (mat/carpet), the foam tires on the RM-01 should provide plenty of traction.

I’m actually going for a 4WD transmission the RM-01 is RWD. I’ll edit the main post to add this detail!

[Help picking lightest Tamiya chassis with best grip for indoor racing]

Hello guys,

I am building an autonomous car that will be driven indoors. The surface is made out of matts (so I guess closest comparison would be clay material?) and has some inclines and declines (no bankings). 

We are aiming on getting the best lap times so a light chassis with a good weight distribution for good grip is required and after searching the web I did not get very much info on the chassis’s below. 

I would really appreciate if I can get some help from you guys on the chassis choice and would appreciate some tyre recommendations too!

My current options are:

-TT-02RR

-TT-02 Type S

-TB-05 PRO

-TB-04R

-TA05-VDF

Edit: Any other option within the $200-300 range and is 4WD is welcome!

Thank you!
