Just to add my 0.02 cents, having had the GTI front springs I wasn't very impressed with their handling on the TDI.
With conversations with spring experts, my conclusion is that the GTI front springs are not meant for the weight of the TDI engine, spring ratio will be wrong.
Part numbers are...
Just to show that this setup does work for some more extreme wheel setups, here is the car riding on some 19" wheels. They are 8.5" in front and 9.5" in the rear.
The tires are quite large size too.
Front tires are 235/35r19 rear are 265/30r19. It only rubs a bit hitting bad bumps in the road.
Made a crappy animated GIF showing the H&Rs vs stock GTI. It's not exact since the cars weren't in the same position but it shows that the front is a basically the same and the rear a little bit lower.
I'm not sure, myself I have ordered the TT spring pads as a precaution, supposedly the VWRs are only a 1.18 drop in the rear and to my eye that would look just about perfect with a proper setup in the front.
Just wanted to Post here what it looks like for quick comparison.
Golf TDI on stock springs
Golf TDI with DG springs (Driver Gear 1.8T springs)
Golf TDI with VWR springs ( VWR31G7BA )
Golf TDI with H&R springs ( 54786-2 )
I checked H&R and the Golf SportWagen with beam axles uses part 54788.
The Golf with beam axle uses part 54786-2 so they are indeed a different part number.
I haven't see any reviews of the 54786-2 on a normal Golf. I'll take the plunge I guess and hopefully it works out. Otherwise I'll have...
