i have mailed hpa,
I have a few questions for you.
Does the competition controller engage 4awd permantley or just when needed (like a normal controller fwd) and under braking?
i have seen this quote on a this thread HPA Motorsports Haldex Controller for MkIV R32 / Mk1 TT
HPA will match or beat all competitors' prices on Haldex...IM or e-mail me for a quote.
i have seen this Audi/VW Diff Controllers | Haldex
Do you do group buys? and if you do how many would be needed and what sort of discount could we expect?
Could these be sent as a trial product to see if they work with our cars?
