Sprint Booster Help

Can someone please explain to me what a sprint booster is + what it does in simple terms? :smile:

I have had a search and I can see that most people say its worthwhile buying one but I just wanted to know what it actually does :innocent:

Cheers:biggrin:
 
£160 delivered mate, its a price ive agreed with Motorsport Wheels for the future purchases, we would need a large number of people for the GB to bring it down like the first time I did one and it had 30 people on the list lol, must have been the most successful GB in history :smiley:
 
Hi guys do these things really make that much of a difference if so I would like to get one :thumbup1:
