After having my arse fed to me on a plate last night by a hyundai coupe bag of crap on a round about i wanna sort this handling out. Dont worry i killed him after the roundabout

boost!
Current mods ARB , vrs beam bushes, rear boot beam, tt front bushes, poly dog bone mount, s3 lower brace, strut brace. Current suspension srt koni 40% uprated shockers and h&r 35mm cup springs. Only a year old.
Now im not wanting 80mm lowering etc. Im keeping this as a daily comfy driver etc but happy to have it harder!. Now i want to lower to 40/45mm as the kit i got wasnt for gtis so really im only lowered 25mm or so

Now got upto 600 to spend. Seen spax adjustable kits which are shockers and springs but with 28 dampening settings had a simlar kit on last car and really could tell when knob was adjusted. About 410 delivered and lowers 50mm front 45mm rear.
Or for another 100 or ao can get spax coilovers 35mm rear and 20-80mm front and adjustable dampening.
Anyone got experience with these? Or any other recomendations to sort the bus handling out?
