Hi Spec 315mm Monster 6 Conversion kits

HI Spec 315mm Monster 6 brake conversion kits are a fantastic way of increasing your braking performance at an affordable price. Hi Spec brakes are manufacturered in the UK and are hand made for each customer to your exact specification. We can provide this with a vast range of colours, disc styles and pad types. HI Spec Motorsport have been established for years and have won many engineering awards for their products.
We strongly recommend upgrade the front brakes on your vehicle before looking at other braking solutions or rear kits. A high percentage of the stopping power is achieved through the front brakes and should be more powerful than the the rear brakes. The size of the caliper requiered will also depend on the size and the weight of the vehicle they are being fitted to.

When I was in need of replacement seats... read moreWhen I was in need of replacement seats for my track car due to my existing seats giving me back discomfort I knew I had to sit in new alternatives to find out what models were best for me.
I made an appointment to see Felix at the showroom so I made the trip to Nottingham where he gave me all the advice and time I needed to sit in each and every seat to see which ones best suited my needs. Eventually after much comparison I was delighted to purchase my new seats along with new harness’ knowing my back, comfort and safety were all taken care of.
They arrived only days later where they were fitted to my car and I can safely say I’m very happy with the result.
Thank you so much Felix and GSM Performance for your help. There aren’t many places in the UK where you can try a large range of products like I did but GSM are one of them and I can’t recommend them highly enough.
If you’re in need of a new car seat or harness amongst other motorsport parts the get in touch with GSM Performance, you’ll not be disappointed. 10/10 read less
