Becuase they are mostly Honda people...

Are they planning to go the other way, like 3.5-3.7 area, for those that may be going the FI route. Taller gears will work out good in those applications for TQ/wheelspin management. Thx

They probably will if it's requested. You can do that with OEM toyota gears already.

Or just launch in second.

Great to know, thx. Which Toyota vehicle do they interchange with?

what's a reasonable price to expect to pay for installation?

IS I think. There's a thread on here from one of the Toyota employees I'll have to look for.

Here's Toyota part numbers for a few FDs that would work:
41201-80050 - Ring & Pinion Gear Set, 3.727:1
41201-80052 - Ring & Pinion Gear Set, 3.909:1
41201-19605 - Ring & Pinion Gear Set, 4.100:1
41201-29606 - Ring & Pinion Gear Set, 4.300:1

tester/early adopter pricing available?

Price and availability?

Any chance a 5.11 will be available?
