Here in South Africa it can take weeks, if not months to get control arms made. I had it done a few times and actually give up. I would compromise for my own car and order parts from here and change the chassis accordingly:
Uses Racing Suspension | RoushYatesParts.com
Used NASCAR Parts and Used Race Parts - Circle Track Supply, Inc.
If I can get controla arms, hubs, spindles and brakes from the US, I am much earlier on the road. Within a reasonable budget.
My thinking may point towards what FFR builds. I need to get to a better internet conenction to look at their site. I have a pair of their adjustable front upper control arms here.
