Well that's good, in which case I'd suggest contacting them directly through their usual channels since (and I know I'm being paranoid) we can't guarantee "Mike" actually works for them.

No, at the end of today we still have 0 options :(
It'll be pouring when all three options are on the shelf ready to sell & ship.

Yeah, at this point, I would have to agree with this, and until they are in fact on the shelf and ready to ship, I'm not going to get too excited about it.
However, I do remain fairly optimistic about it actually happening though....

Anyone who has any concerns, can contact Quaife UK themselves for confirmation that these are indeed in production for us:

https://shop.quaife.co.uk/contact-us

+44 (0)1732 741 144
info@quaife.co.uk

No payments will be taken until the units are here, I will post up in a separate thread nearer to the time. These Quaife units will happen 8) . We've got good interest in half of the units available thus far.

Again apologies for jumping onto your thread Eric.

Thanks

would the center diff be configurable to 1.5? it seems 2 way might be too harsh for tarmac driving causing under steer going into a corner.

I do know on the Cusco plate LSD's you can change them between two different configurations by changing the ramps, but not all of them are....

personally I feel 1.5way would be better for tarmac and gravel.....I guess we will see what the specs are?

I wonder if we all specified on the Google document which we prefer perhaps they may take that into consideration...

Now if somebody could build us a sequential kit with rally ratios. Like maybe Samsonas or SQS. I will probably build SQS H pattern dog box next.

Would be next to impossible to change a H pattern to a sequential, the actual design is so different in terms of gear selecting, but I hear what you're saying.....You can buy a Maktrak which is sequential, but huge money....

All is not lost though, SQS does a sequential shifter which uses soleniods on a conventional H pattern gearbox for gear selection.
So the combination with the SQS Dog kit (where you can choose your final drive and ratios) and their own sequential add on, its all there.

They will need to fabricate a case and internals with a drum shifter like they do for Evo.. MacTrak is an Evo box installed on Celica with his adapter plate. You get into big money with transfer case and rear diff.

I've been in touch with several firms about sequential transmissions... Maktrak is out of business, the owner passed away and the business closed down... Our options for 6spd sequential are limited and exorbitantly expensive...

In our rally shop we did business with Samsonas. They will do it of we get enough units ordered. It's no different then evo. And the only reason evo is so inexpensive is the numbers they make and sell.

How much is an Evo unit?? Maktrak used the same trans for us and Evo. The Celica's either had a diff bellhousing or just a BH apapter plate... the problem was the front diff ratio's available for the Maktrak dont match our rear diff ratio(2.929 if memory serves correct) and would require using their rear diff assembly(add $10k), have a custom ring and pinion made, or possibly swapping a Supra rear diff which has more ratio options but still requires loads of customization. My main concern aside from cost is serviceability... if I blow my trans at the track i'm screwed and down for how many weeks shipping it back and forth to whomever for repairs... it's a lot easier and hella cheaper to have a spare 185 or 205 box to use as a spare...

The front diff gear ratio [which is the final drive] is completely unrelated to the rear diff ring/pinion gear ratio.

The gear ratio on the front diff is the final drive. Power is then transferred to the ring/pinion gear in the transfer case; which lowers the drive speed so the driveshaft spins slower. Then the rear diff ring/pinion gear raises the drive speed back to the original speed in the transfer case, so the rear wheels spin as fast as the fronts.

The transfer case ring/pinion gear is what matches the rear diff ring/pinion gear, not the front diff.

I only stated what I've read, heard from other GT4 owners, and what Maktrak also agreed with when we were in discussions about my options to avoid buying their rear diff assembly. The transfer appears to use a bevel gear and the center distributes power to the front and rear... Besides the front and rear ratio's would still need to be identical or the center diff would burn up front the front and rear spinning at different speeds. At least that's my understanding...

My understanding is that with maktrak you are replacing not just gearkit but entire gearbox and transfer gearing meaning ratios exiting to rear may well be different
