Unashamed plug for these guys.
Had the alignment set up again yesterday, after I'd had to remove various suspension components to renew both rear springs on my TT. The attention to detail and quality of workmanship Brad provides is outstanding!
Everyone that works there are very genuine people, welcoming, take time to explain exactly what's going on, and why.
I'd highly recommend their services.

You don't mention if your TT is a Quattro or 2WD version - for RRS and most permanent 4WD SUV's special equipment is required to carry out a 4 wheel alignment 2020 Pangea Green 1st Edition D240 New Defender 110 is here and loving it

2015MY Corris Grey SDv6 HSE Dynamic, the best car I have ever owned, totally reliable only a cou0le of rattles in 3 years, now no longer in my care
Also in my garage is a 1996 TDi300 Defender 90 County HT made into a fake CSW

Yes, it's a Quattro. They use a Hunter HawkEye Elite set up.
On my first visit just over a year ago, they didn't have the special tool needed to set up rear camber, thrust angle & toe. Brad managed to still get it within tolerance. This visit they had the tool (which broke while in use.) This wasn't an issue, he stripped it down, figured out why it had broken, repaired it, rebuilt and carried on as normal!
Safe to say, through his knowledge, skills and determination to do the job right, my TT is travelling yet again dead straight. Daily... Audi TT 240 qS, tasteful mods.
