1/8 scale on-road questions

[lincpimp]

So I am looking at building another speed car, and would like to scale up my 1/10 scale car. I have a body style that works great (lola), and can get them for the racing style 1/8 scale cars.

What I am looking for is a list of these types of cars. I know mugen makes one, but who else? Schumacher maybe?

I would just use an 1/8 buggy based 1/8, like the GTP. But they are too wide, and not really sophisticated enough for my liking...
