I was wording the YFC bit in my head, then- Ahahaha! New cars have no soul! look at the height of the roof line against all the modern stuff and they are like removal vans in comparison next to the old Supra. Drag co effeicient is sod all too, so they just glide through the air quite nicely on a cruise. Get a bit sketchy around 140 though
As for your diff, i suggest getting the cover plate off and have a look what's lurking in there. They are crap for doing donuts in as stock though due to the mega soft suspension.. bang 50psi in the rear tyres and that'll should get the arse round.
D-rifting R-usty I -credibly F-unky T-yota's o- f Y- esteryear
Saying that the mazda is a 7 seater and it proper goes round a corner Lol.
Will take a look at the diff at a later point as it isn't priority. I had a read through on your exhaust advise and i'm going to copy that apart from a twin exit. All good stuff Neil, making my life easier.
