Default Tyre decisions - Input welcome!

Hi guys, I'm trying to decide what tyre to go for on my EP3 it's setup pretty agressively so need a tyre size to match.

Currently as pictured i have 225/45/17 RE070's on a 17x8 enkei wheel.

I have 215/45/17 x 2 Toyo R888s in the garage for the rear and was going to run 245/40/17 up front in Toyo 888s but would this work ok on a 17x8 rim?

Other option is to stick with 225/45/17 but in a R compound.

What would you guys go for in terms of optimum performance?

I also have 15mm front spacers here to fit to widen the front track slightly

my chassis modifications and GEO specs -

Chassis and Suspension

SuperPro Caster increase bushes
SPC rear camber arms
Buddyclub N+ coilovers
Progress 24mm Rear ARB
Buddyclub roll centre adjusters
Steering rack raiser
New steering arms and track rod ends

Current GEO settings:

-3 front camber
+3 caster both sides
0.8mm toe out per side

-1.8 rear camber
0 toe

Wheels and tyres:

225.45.17 RE070's currently fitted on Evo Enkeis
15mm front spacers

Heres the car,
