When we had a 25.5 side by side with a track full of 21.5s, the 25.5 was about 0.2sec slower on a small asphalt track. We had the timing wicked all the way up (it was an SS) and the gearing was about 0.75FDR numerically lower than the 21.5s. Visually, it was barely slower, but it did manage to win the B-main with a consistent driver.

I think the TC3 or Losi XXX-s shocks will work...Ive seen ppl switch them off the HPI S2S, not sure with what brand...you might trying the HB site for maybe the Cyclone series Tc cars

Comparing a 25.5 to a silver can is kind of moot. A good silver can will hang with a good 21.5. A really good silver can will smoke a 21.5. No timing on the 21.5 of course.

A couple weeks ago I switched my VTA from my S2S to a Cyclone TC. While trying to get a good race setup on the Cyclone my car would push on/off power on left turns and would be very loose on power on right turns. I tried everything I could to get the problem to go away, different springs, lower roll center, bearings. I went back through the basic setup and corrected a couple very minor setup issues, front camber was off by .5* and re aligned the steering. I even swapped shocks side to side just to eliminate those. Nothing that I did would correct the problem. That is until I swapped tires side to side then it did the opposite of what I started with, push right and loose left. So it seems that I have a bad tire or insert on my car. I am not worried about which tire is bad because I have a new set of tire glued up and ready to go. I was just trying to wait to use them until we started to race.

Getting my parts together for a VTA.
Picked up a used Xray T2, vintage wheels/tires, Mustang body from amain and a Havoc 2s/25.5 Ballistic combo from Novak.

Looks like some guys just over the border in Canada are running these so I hopefully have a place to race.

Default Ride Height Question

Hey guys, we are trying to get a VTA class up and running and I have a question about ride height. I see the rules specify 5mm minimum ride height, is this measured at the lowest point on the chassis, or does it also apply to the body? The pictures I have seen seem to have the little spoiler at the front of the cars lower than 5mm.

Thanks

Usually, all parts of the car would be subject to a 5mm minimum. All points of the chassis and body.

I was going to say the bottom of the lower deck. Chassis plate. My front lip may go lower than that sometimes, but I think its usually flush with the lower edge of the foam bumper, which is perfectly in line with the deck. I believe the rule is to affect the handling characteristics of the chassis and the deck is much more crucial than the front lip. I think Tim Ski probably has a lot more experience with that than me so until you hear from Robk I would go with what he said.
