Default 1990 LS400 Brake upgrade

I am going to upgrade the front brakes to 4 pots.
I have seen Supra kits advertised for £600.
I have priced up 95-2000 LS 400 kit at about £450 + shims + pins. but then I believe a set of lower ball joints is needed, then it will need tracking so the price difference will be negligible.
So which is the best value for money?
Which need least wheel clearance for the calipers?
I have 10 spoke GS300 wheels on and with the std discs I have 66mm clearance

Will 95-2000 LS 400 rear discs and calipers fit the 90 ls 400?

rears should fit but are the same size so arent an upgrade.

UCF20 fronts should be cheaper than that, in the US the going rate is ~$300-350USD for a set incl. rotors used.

ucf20 rears are an upgrade on the 90-92, on 93-94 they are the same.

it's a shame you're not close op, i have a complete and customized 90-92 setup with low miles way cheaper.

I would be interested, at least in the rears to start if they clear the standard 91 wheels? Since I only run the volks in the late springs to late fall.

As I said the cost difference is negligible. If I buy refurbished calipers, new discs, new bottom ball joints, new fitting kit and new shims it will cost be about £550. I can get a supra kit for £600.

I may be tempted to buy the supra kit if its less messing. but i need to know if the calipers will fit under my wheels. How deep is the supra caliper from the disc surface to the face thats says "supra" on i

the LS caliper is wider but much lighter (completely alum, the super caliper is half steel)
