I have shockworks brakes on my fg .
6 pot 380mm on the front and 4 pot 335mm on the rear.
Im really happy with them.
I think they were around $5500 delivered. That was the middle of 2022.
No , just make sure your injectors and fuel pump are suitable .
I had similar mods to you and the car was good for 11.2 @ 124mph on e85 .
I'm in nsw and last time I filled up I think it was $1.40L
Suspension . I haven't had wheelspin at the track since having shockworks fitted and running m/t et street radials.
3rd gear burnout and it hooks up all through first. Car has run 10.2 so far.
Can't really comment on wear as I only drive the car on the weekend.
Best tyres I've used .
I'm still running the factory wheels , 245/35/19. Really happy with the grip they provide . Nice turn in and great straight line grip.
If you're interested in a PW stage 1 stepped cooler for cheap let us know .
It's been sitting in the corner of my lounge room for the past year , just haven't got around to selling it .
Have you tried driving the car with that size tyre.?
If you haven't , take a drive around the block first and see if the abs cuts in prematurely . You might have to pull out the abs fuse .
