1/10 Onroad/rally car?

[IGT_7x]

Tamiya makes the DF03ra chassis which is specifically for rally purpose, that could work for what you're thinking about. Here's a link.

Of course there's also the Kyosho Inferno GT with the Subaru body, they can go insanely fast once converted to brushless, I know, I have one but that's 1/8 scale.

Also there's a crap load of hop-ups for the DF03ra on RCmart.com. You can use most of the hop-ups made for the DF03 also as this is the exact chassis the DF03ra is using, the only difference is the shocks/towers are shorter.
