600+bhp GR Yaris mods and maintenance

Pete’s 600+bhp Garage Whifbitz built GR Yaris back in the workshop again.
This time for a Quaife ATB LSD rear diff as the Yaris is a non circuit pack and comes with an open diff from the factory.
Whilst it was here it’s had engine, diff and gearbox oil change along with a new set of HKS spark plugs.

Watch out for this GR Yaris drag racing on the OfficiallyGassed YouTube channel soon.
