ManwithSupra Posted June 9, 2010 Share Posted June 9, 2010 (edited) A conversation i had with one of my mates (who is after DBA discs for his car) and Paul at Whifbitz got me thinking... The DBA 4000 series discs for the Supra the 4418XS and 4419XS do they really warrant double the cost over UK OEM Discs? The 4418 and 4419 have DBA's "pawprint" cooling design and the discs are Drilled and pitted? But how much more effective (if any) are these discs over UK stock discs the only difference i can see is the look.... are they really worth twice the price!! Any comments welcome.

Nic Posted June 9, 2010 Share Posted June 9, 2010 There will be no difference in braking performance between the one piece DBA discs and stock discs. The 2 piece DBA discs will have a slight weight advantage over stock. Quote Link to comment Share on other sites More sharing options...
dandan Posted June 9, 2010 Share Posted June 9, 2010 There will be no difference in braking performance between the one piece DBA discs and stock discs. That might not be 100% true Nic....the surface features on the DBA discs will likely affect the initial bite - much like the J slots/mini curves etc on various other discs like AP/Alcon etc. Also depending on the vane design in the vented portion, heat loss may or may not be better than OEM. I believe the internal vanes on the OEM rear discs are straight - there could be improvements here with the right design (I do not know what the DBA internal vane structure is like though).

a98pmalcolm Posted June 9, 2010 Share Posted June 9, 2010 (edited) I have DBA slotted disks, i got the best ones i could that would fit the supra from DBA and they seem pretty good to me! Dont go for the drilled ones! even the guy at DBA told me not to lol Here is what mine look like (j spec brakes) front: Rear: Edited June 9, 2010 by a98pmalcolm (see edit history) Quote Link to comment Share on other sites More sharing options...
Kirk Posted June 9, 2010 Share Posted June 9, 2010 Curious as to where you got them from and how much they cost?? Quote Link to comment Share on other sites More sharing options...
Geo Posted June 9, 2010 Share Posted June 9, 2010 Id defo recommend the OEM, CW, UK caliper set up. or if you have the cash splash out on AP, Brembo etc. THB i dont think anything else is worth it. Toyota didnt spend shed loads of money on R&D for there brakes, for us to change them for something else. Quote Link to comment Share on other sites More sharing options...
Kirk Posted June 9, 2010 Share Posted June 9, 2010 DBA discs would be the only other disc id use next to OEM to be honest as the internal vane design is probly alot better than conventional straight vane design but i await to be corrected Do AP make stock replacement discs?

I'd also consider Project Mu and Endless discs. I use to use the Project Mu SCR Pro discs, not cheap but quite a bit lighter than stock and very hard wearing. http://project-mu.co.jp/images/photo_rotor_scrpro.jpg Quote Link to comment Share on other sites More sharing options...
ManwithSupra Posted June 10, 2010 Author Share Posted June 10, 2010 I will probably stick with OEM UK Discs until i buy the Whifbitz AP front and rear racing setup to be honest. I cant justify spending twice the price on discs that really offer little upgrade in terms of braking performance, so i may as well put the exta money towards Whifbitz AP racing setup.
