Calipers Arrived - UCF30/LS430 Sumitomo 4pots

<-  Toyota Celsior UCF30 or Lexus LS430 '00-'03 in USA, which i plan to run with some 1997 Mitsubishi 3000GT 314mm discs cross drilled for the Colt

Weight is 3.8kg each, no pads, lines or pin retainer

As seen here, it was always a plan of mine to try some /ls400ucf20-or-ls430ucf30-front-brake.html

Some of the weight i had, guess like horse power you can't really compare.
No idea if people weighed it with pads or without etc
And you can find multiple weights per caliper @_@, makes comparing really hard



To the right are the brembo caliper adapter :)
Another possible project


UCF30 = 3.8kg (weighed myself)
EVO8/9 brembo = 3.7kg
Ksport 8pot = 2.9kg
Z32 NA Iron= 4.4kg
Z32 TT Aluminium = 3.2kg
Z33 brembo = 4.0kg
R32 GTR 296mm x 32mm (4 pot sumitomo caliper) = 3.2kg
R33 GTS-T = 3.2kg
S14/S15 = 4.4kg
Wilwood Dynalite 4 pot = 1.46kg (no hardware)
Wilwood FNSL6R 6 pot = 2.2kg (no hardware)

What you see are my new 294mm discs DBA417 re-drilled to a 4x114.3. What a rip off a redrill costs, gotta teach myself how :)





However these are not for the UCF30, but they are for my special caliper adapters.
These discs have been awaiting fitment with the caliper adapter mr307282, as seen here long ago... /z27ag-rcolt-mr307282-with-294mm-discs.html
