Rollcage introduce me into DnB and Darkcore sound... and I still love it... but perfect was the divergence depends on racetracks... for deeper industrial look there was great Technical Itch and Dom & Rolland (where great alternatives are Switch Technique or Stakka & Skynet) for lighter themes there was aslo great Aquasky or Omni Trio.
I hope that you will bring this feeling back too.
If you want some frash more modern sound there was mentioned Noisia with some overlap to Dub Step. Or Savant (Aleksander Vinter) which is great musician with lot of different setups. For example Ninur album sounds great for me (it is bit darker then rest of his production) and I also love his complextro setting but I sure that is not good choice for Grip.
And even if I am kind of a fan of dub step... I am not sure if this is a good choice for Grip... When I saw the first trailer I was almost transfered back to my childhood and there should be the (almost retro today) same soundtrack.
