I just can’t recommend Shoptimizer enough. I feel like I’m on a first-name basis with some of the crew, they’re just so unbelievably helpful, no matter what the question. Their products are also so beautifully well made and easy to maintain, they’ll last for years to come.
Every order from Shoptimizer has been an amazing experience. their site provides lots of detail so I know exactly what I’m getting and their customer support is just outstanding. I needed to swap an item for a different size and they arranged everything for me within 24 hours.

What our customers say
I only have good things to say about GSM. Excellent customer service, very patient with multiple exchanges for an ill fitting OMP helmet, and fast delivery & dispatch every time. Every interaction with the team was great and their pricing was very competitive so we’ll definitely order again. Thank you for making an ordinarily irritating returns experience really easy.
I run a motorsports charity called Baronmotorsports and with the help of gsm I've managed to get seats harnesses and towing eyes all under the price of one quality seat thanks so much for your great help in store Regards Steve
