    Roll restrictor

    Made to feel welcome from the minute I got to the reception and spoke to Ryan, who was a great help and gave me a breakdown of everything I’m gonna need, thanks so much to everyone at Mountune

    Had this fitted along with the cat-back exhaust and induction kit and am really impressed by how much difference this seems to make. The car now feels planted when accelerating and changing gear and I've not noticed any wheel hop like before. There was a bit more vibration than before at idle but I was warned to expect this and that it would ease off as it bedded in, seems fine now after doing a few hundred miles. Really happy with this, given the price this would be well worth it even if it was the only mod made to the car.

    Great product - outweighed by a great service!

    From the facilities, the confidence given from Ryan who handled my request and the team that fitted my item - could not recommend these guys enough!! I had a complaint about my car, which the team resolved and put my mind to rest; whilst my item was being fitted. Comfortable facilities (free snacks, drinks and Xbox too)… Just looking for and excuse for a return visit!! Thanks again Ryan/ Team; one happy customer here, and the roll restrictor sorted out my annoyances!
