I have friend who use a R18 on motonica P8C too, him happy with it. But we don't have same car. I have a forfaster Z1. My R18 pf is at 20mm from front bumper. I have try 10mm. But still the same problem, no rear traction and stil a lot of steering with guerney strip at 10mm.
The best body i used become from forfaster, its look like the R09 blitz, but with a cockpit at 0mm from front bumper. But to hard and expensive to have it(from italy).
The problem with pan car 1/8 and 4X4 1/8, we dont mount the bodyshell at the same position from the front of the bumper
I can have some Blitz ARX for a very low price. That's why my question here. If someone can advice me about this ARX bodyshell.
@Johnson40, Thank you for your reply, i think your rear tires are to much soft. In france, we never use 32° at rears or maybe if the track have some wet parts.
Becarefull with ufra too, the shore isn't so good, i bought some 35° rear. It was 32°. I made the comparison with other brands(matrix,enneti,contact...) and a meter shore.
Im sorry for my english.
Sorry, im French ;)
