I have my XV01 and TA02 that run high ground clearance and larger tires. The XV01has 74mm tires and sits about 16mm and has a max height of 21mm. The TA02 (which is now NOT getting the Suzuki body) stays as its T variant with its 88mm tires, riding 21mm high with a max of 31mm. The TA02T can handle grass too, as long as it's not too long. So those cover the need for really bad pavement driving. I want to keep this one as a more true-to-life rally car - good for pavement and loose dirt, and what would be scale gravel.
Giving the TB04Ra a shakedown run, I have noticed that its turning radius is quite large. It's not my servo settings; the farthest the steering will turn to either side isn't very large. I can see the need to keep the steering from getting too tight as there are the mounts for the IFS that could get in the way. This is just something I noticed about the chassis.
