Engine mods for gti6 track car

[Day666]

Think the 4.4 was worth maybe 3mph on combe main straight. You gain steering lock too if you change the pas ram

B8s and eibach are too soft for a proper track car. Decent coil overs, more camber / caster depending on which diff and tyres

My car has set me back 3k but it has only very mild engine mods (it's a gti6)

I'm running b8s & Eibachs on the front of mine at Combe & can't fault them ?
I'm told the rear suspension setup is just as important on 306s ?
The Plate diff I agree from Miles made the biggest difference .
Never get into 6th on track days ...
