im using those with Omp pads, they can stand my abuse been to Le Mans on a roads round some of the track had some really hard stops and they are fine
From Mulsan around to Porche Curves, pity they won't let you do the race route down the staights instead fo forcing you around the roundabouts.
Did you get the OMP's from the same place in chesterfield an how much?
I must admit I was almost tempted by the kwick Fit deal, new pads for life but they quoted just £68 for pads (they say made by brembo but they don't make the pads???) and do I trust them not to damage the paint on the calipers, I think I will give it a miss.
