I run a Vega RB5, I tried Matt Owens car once and was absolutely sold so ordered one straight away from Kev at Insideline...
Since i've had it, I only have one gripe, the rear shock tower has a weak spot around the camber link holes, they are just too close together... I'm getting some more made with the holes spaced out and with a bigger rad on the lower mounting cluster.
Otherwise the car is awesome, two more have been sold based on mine and I would recommend it to anyone..
