One of the reasons that VTA isn't 2wd is because the current HPI Vintage tires don't fit on any of the readily available rear-wheel drive 1/10 scale vehicles. About the only 2wd/rwd vehicle available that uses touring car tires is the Tamiya F103gt. Unfortunately Tamiya discontinued that vehicle. Here is a link on Tamiya's website (http://www.tamiyausa.com/product/ite...oduct-id=58367).

Another 2wd vehicle that can use standard touring car wheels is the HPI F10 - F1 chassis. The F10 dimensions are more narrow/longer than a standard touring car chassis. However, I have put the rear axle and front steering knuckles from the F10 onto a 1/10 scale pan car (Associated 10L3O) and they fit well. I have posted some pictures below.

The only r/c on-road class that uses front engine rwd bodies on rwd cars currently being raced is World GT (WGT). The chassis are 200mm pan cars using foam tires. There is a thread here on RCTECH.

The best reason for using 4wd touring cars for VTA (in my opinion), is that just about any 4wd touring chassis currently available (new or used) can be competitive in this class. Also using 4wd cars allows us to easily race on any surface, such as asphalt or concrete outdoor tracks.

Remove the belt / shaft and you have instant RWD

Put a one-way in backwards. 2wd, but 4 wheel braking.

I raced my VTA car for the first time today against 8 other drivers. That was more fun than you should ever be able to have with an R/C car!!! A little fender banging, swapping positions in the turns, and close finishes made for awesome racing. This class is a blast!!

Same reason VTA allows new underpinnings while trying to maintain the appearance of being vintage racers when they're not = "dem's da rules"

Awesome! My VTA car was supposed to make its debut yesterday as well, but we got rained out. So a few of us found a parking deck and went drifting instead.

My old TC3 that I just revamped for legal VTA specs was originally in 2wd form and had a RWD 240x body on it. Handled pretty decent with just RWD too, had some tendencies to want to drift exiting the corners which is even more realistic. I wouldn't say converting all current platforms to run 2wd is the best way to go though.

modified or option motor parts.

Motor Specifications:
25.5 brushless with 2C LiPo: Novak SS25.5 Pro brushless motor (pn:3425V) or Ballistic 25.5 (pn:3625V- stator only pn:S6625) Club (pn:3331) ONLY combined with any hard-cased 2C 7.4v LiPo pack up to and including 5000 mAh capacity. Novak motors are the ONLY motor allowed at this time. All house track rules regarding LiPo usage apply. Only physical motor timing advance is allowed, however Ballistic motors must not be advanced beyond the last line of the timing range sticker. 12.3 mm rotor diameter only (no "tuning" rotors are allowed, only stock Novak rotors allowed). Using ceramic bearings in the motor makes you a dork. No modifications or optional parts allowed on motor can, endbell, stator, or rotor. No cooling holes or other changes allowed to motor. Fans and external clip on heatsinks are allowed, but integral type heatsinks/fans including but not limited to those that require motor disassembly to mount are illegal.

Is there a smaller capacitor that will work with the GTB2 other than the behemoth it comes with? Novak of course always recommends the stock cap, but I wouldn't be anywhere close to the esc rating running it with a 25.5 and that thing really is in the way mounting it in the car.

Unsolder it - add some wires - relocate it... Done.
Anything less than what came with it and you're probably looking at problems...
