do you have a GR?
tibor has been making his rack assembly for GRs for quite a while.
have you spoken to tibor (q-rack) at all about his available options?
he has two options available for the GR. most popular is the faster 11.5:1 ratio and i've never heard any complaints from drivers with it installed about it being too fast. they obviously also have the slower 12.5:1 ratio rack.
on a GH/GE, we don't have the luxury of partial on/off, obviously. it's all on or off. last i talked to tibor, he didn't have a solution for the VDC issue on our models. sure we can pull the fuse for the VDC but it is the same fuse for the ABS.
for more information on the issues/solutions and installs on the GR/GE/GH, check out:
i've been in communication with Tibor for at least two years now off and on and think i'm at the point in my build that within the next couple months i'll be picking one up for testing, if you want to hold off. if not, give it a shot and please post up!
