What are you looking for, just 4 wheel alignment, or alignment + camber + caster + toe?
Wherever you choose just make sure you get a print out of the results. That way you'll know if what you've got is right for you and which way you may need to go (with advice on here if needed) to get it how you like it.
Got camber bolts ? Rears don't have any. Caster cannot be adjusted. So your effectively paying for toe front and back and camber on the front IF you have camber bolts.
I went to JamSport and they're severely overpriced. Why didn't you go back if it didn't feel right ? I did and they re-aligned FOC.
I can suggest Corby Tyres in Corby. They have a hunter system. Quoted me 90 + VAT for Toe and camber front and back on the CTR.
So for toe and front camber, you'd be looking about 60-70 + VAT at a guess.
+1
And make sure the donkeys don't just get it in the green in the middle and then talk balls**t about the overall toe and camber. You want EXACTLY the same both sides.
Some places charge £100 up! Thing is they must get people paying for it!
