I had a Hollinger it was great but there service was rubbish minimum of a 3 week wait for anything.I had no dramas but I didn't do a lot of work did some street driving maybe 20-30 passes at the track and I did a trackday
I have now upgraded to the albins I'm extremely happy with the albins there service is amazing I had 1 issue and the part was flown up from Victoria and car was on the track the next day. The gearbox has not missed a beat has been in my race car making 530kw atw and I have put it in my street car which has been up to 1044hp atw
but the down fall is the tunnel has to be modded literally a section cut out and fabbed new one to be installed
