All I've done to my manual ED30:-
Remap to 1.4 bar (0.9 is standard). All this 'stage x' is just marketing speak. It's just upping the boost pressure at the end of the day.
Helix clutch & new DMF
WALK
Just those 3 things have given me a daily usable 320hp car that has all the ride quality and refinement of the standard car, win win
Next year I will be doing a chassis refresh to OEM spec. New dampers & bushes all round to get it back to a new as possible feel. I think sometimes people forget how good these cars were when new. I went out in a GTI recently that was lowered and big brakes, big exhaust, all of it. It was bloody awful. Getting back into mine again was a breath of fresh air.
I'd like to hear your opinion after you tried mine. Unfortunately I'm too far for it to happen easily. I think mine is a better daily driver than the OEM spec. I've done it 1st to my GT Sport, I just had to go up a notch for the Ed. 30.
Would love to try one with all the nice quality bits. Not sure what this car had on it but it was crashy, droney, too much intake and turbo noise and felt a fair bit slower than mine off boost.
What suspension have you got on yours? Instead of refreshing all the OEM stuff, I was considering the Ohlins Track & Road setup but it's a lot of money to sink into an unknown entity. At least with the standard stuff I know where I stand, and quite like it too
I kept the OEM airbox, so no intake noise and I have a BCS Powervalve TBE Prestige system with 200 cell cat, so no drone and just great exhaust sound when on boost and pushing the engine.
If you like the height of your ride I'd recommend Koni FSD (the kit 2100-4001 is for normal Golfs so not as harsh as the kit 2100-4090 for GTIs) and Eibach Pro-Kit springs, that I've fitted in my GT Sport with the same sway bars as the GTI.
In my Ed. 30 I've fitted Koni Sports, H&R -30 mm (29176-1) and H&R front and rear sway bars (33258-1) 26/22 mm. The suspension was setup by my mechanic to be able to take bumps without being too harsh. The car can make fast turns really well and has a lot more grip than before with OEM shocks and Eibach Sportlines, that made the ride too bumpy over small to moderate road creases.
I'd love to get those coilovers for my Golfs too, but I've spent a lot less and I'm happy with the way they are at the moment. I hate harsh rides.
