Hi gents,
As it stands, my 2002 Galant 2.5 v6 Elegance (EA5A) has single-pot front calipers and 4 stud 275mm diameter discs.
It's in need of new front discs/pads so I thought before I go about ordering parts and doing the job I'd ask if it's a feasible 'bolt on' job to
upgrade the front single-pot calipers to twin-pot calipers.
From trawling the forums here, I've got the impression that this may be a simple caliper swap, but would much prefer clarity on the issue before orderring parts.
Why go to the trouble of changing calipers? Well, there's no Ferodo DS2500 pad pattern available for the single pot calipers but (as VR4 owners will know) there is for the Evo 1-3 and VR4 twin pot calipers. I'm hoping to be able to have twin-pot calipers with Ferodo DS2500 pads and National 8 slot grooved discs (as recommended within the forums).
Being that it's an EA5A (facelift) will the calipers from an Evo 1-3 or VR-4 2.0 V6 Turbo 24v (E84A) fit without having to also change disc stud pattern from 4 to 5 OR am I way off the mark (are the caliper mounting holes wider/shorter between the EA5A facelift and Evo 1-3 or VR-4 2.0 V6 Turbo 24v E84A)?
If the Evo 1-3 or VR-4 2.0 V6 Turbo 24v (E84A) caliper is the correct solution...
i. is this a straight forward caliper swap and will I also need the caliper cradle/arm from an Evo 1-3 / VR4?
ii. does anybody out there know what the mounting hole distances are for 'caliper to caliper cradle/arm'
and also 'caliper cradle arm to hub carrier' on the VR-4 2.0 V6 Turbo 24v (E84A) and/or Evo 1-3 and on the non VR4 Galant 2.5 v6 (EA5A)?
iii. I know the Ferodo DS2500 pad part # FCP765H is identical for Evo 1-3 & VR-4 2.0 V6 Turbo 24v (E84A) calipers and the National Discs standard replacement part # NBD586 is also identical for Evo 1-3 & VR-4 2.0 V6 Turbo 24v (E84A) 275mm diameter discs but the National Discs standard replacement part # for the 275mm diameter discs of the non VR4 Galant 2.5 v6 (EA5A) is NBD1134.
Looking at the National Discs pdf doc, the only difference between the discs is that the NBD586 is 45mm deep and the NBD1134 is 43mm deep,
or am I missing something (like the 4 stud pattern dimensions being different)?
So do I order the VR-4 NBD586 discs or non VR-4 NBD1134 discs if fitting the Evo 1-3 / VR-4 twin-pot calipers?
(I do however know that the part # for the performance upgrade 8 slot grooved discs will actually be PDB586G for the Evo 1-3 discs).
If however I am way off the mark, can somebody please advise which calipers/discs/pads I should be looking at.
Many thanks for your help,
Mark
