Chris Wilson Posted February 3, 2016 Share Posted February 3, 2016 Special offer, £900 plus VAT. For the big diff only. Best LSD's available for the MKIV, transforms the cars, built like a Swiss watch, with spares availability. Big saving, when they are gone, they are gone...

j_jza80 Posted February 3, 2016 Share Posted February 3, 2016 I've got a small case diff, and I've already had a TRD diff fitted to it, so I'm afraid "bargain" is all you're getting from me. Better than me posting 'rip off' though Link to comment Share on other sites More sharing options...

Chris Wilson Posted February 3, 2016 Author Share Posted February 3, 2016 How much would you do these for fitted Chris, if was was to give my big case diff? £120 plus side bearings and side seals which must be changed. Can't remember how much they are, would have to check. Link to comment Share on other sites More sharing options...

SPG Posted February 6, 2016 Share Posted February 6, 2016 Chris, how road friendly are these compared with the TRD units? I am going for a fast road set-up and was leaning towards the TRD, as I thought the Giken was designed more for track use? Also would this be suited for the B03b large case manual j-spec enclosure?

Chris Wilson Posted February 6, 2016 Author Share Posted February 6, 2016 They are fine on the road, but you must use the correct Giken oil. They are for that large case, so that's fine. There must be quite a few people on here with these fitted who can comment on how they find them, I myself have fitted a good number. Link to comment Share on other sites More sharing options...

Jellybean Posted February 7, 2016 Share Posted February 7, 2016 Chris I was talking to OsGiken USA and they also have an alternative oil, just good to know if the OsGiken Oil was hard to get http://www.mkivsupra.net/vbb/showthread.php?328829-OsGiken-Spec-x&highlight=osgiken For oil we have two approved and tested fluids to work with the differential. OS Giken 80W250R and Motul Gear Competition FF 75W140 No LSD Additives required In terms of break-in there is no "break-in procedure" (ie. Figure 8’s) but a recommended fluid change between 500-1000 miles or one track weekend after install. Link to comment Share on other sites More sharing options...
SPG Posted February 7, 2016 Share Posted February 7, 2016 My VVTI TT6 comes with a factory spec'd B03B large cased LSD. Although it's the only one I could find that had this from the factory, it's mated to V161. Pete I'm guessing you have a A02B or A02A if non LSD, as the manual cars came with the A03B in facelift guise. Thanks for the reply Chris, I'll be in touch no doubt shortly Link to comment Share on other sites More sharing options...

Just about to buy one too. Clearly well made and as you said no need for a break in. From their site... "Due to the precision manufacturing, high-grade materials, and unique design, a break-in period nor rebuild is required for OS Giken LSD’s.

Chris Wilson Posted February 9, 2016 Author Share Posted February 9, 2016 My GTS-t was one and a half seconds faster around Oulton in the dry and faster still in the wet, JUST by swapping out the appalling Kaaz LSD for the OS Giken, a few preload experiments gained another half a second. I was amazed, that's a MASSIVE time difference from an LSD swap. Since I was taleked into trying one Giken have now been "discovered" by many high end race teams and a lot of fancy saloon and GT race cars have them fitted worldwide. They really are THAT good. Only comparable LSD is the lovely Tracktive ones, but they don't list a Supra type unfortunately. The difference between a Torsen and a proper plate type LSD like the Giken or discontinued TRD is night and day. OE makers like Torsens as they are silent, no maintenance and cheap to make.
