Yep offroad tyres are completely overrated in the dry. Help but only by a pretty small amount. The wet is another story....

Keep us posted if you do find a 4.11 R180 because from what I have heard they are stupidly rare if they exist at all!

Great... Not what I want to hear!!


Also I'm interested to know what the weight difference of the R180 locker is compared to the "regular" R160.


Cheers

R180’s are plentiful in the 4.4 and 3.9 ratios. Well, not so much 3.9 for the actual diff gears because they are overall 3.9 with the centre diff step down gears. If you have an EJ box, then finding 4.4 gears should not be too hard.

Well, I've got bits of an EJ box... :P


And a little bit of EA in there too for "good measure".

If your still in Perth I'll be keen for back to back tests with my car. I'm standard diffs. The only drive line modification is 1.447 low range. And suspension I have the Hotbits.


I briefly looked into custom made low range and was quoted about $2K for a one of manufactured subaru low range gear set (Scorpion's 1.58 design). Would have to design the optimum gears before spending that money. You'd get 1.74 low range with the front half of L series low range (23/19) and the rear half of a scorpion low range (23/16). I didn't get much further, but I'd be keen to look into lower low ranges with you.

I didn't actually weigh the two but there is not a lot in it. Probably only 5kgs. Put it this way, I could carry both pretty easily and lifted the R180 into position without a jack. I was surprised by the similar weight I am guessing that the R180 being 15 years younger may have a thinner more optimised casting than the R160. They are also not that much bigger.

Pity you didn't go the 4.44s when you did the pinion shaft Bennie!

Sounds like a plan!

Out of interest who did you talk to? And where did you get the details of the scorpion set? Are you certain about the L series ratio. The majority of the L series reduction is done in the first section..
With the 4.44s there is bugger all additional reduction I can fit in the second stage but I could fit a bit more in the 1st stage with my LSD. This is with current L-series low range.

Albin's Engineering who were the manufacturers of Scorpion Low ranges.



Scorpion is front (20/22) rear (16/23)


L series is front (19/23) rear (19/25)


Looking at gearbox pictures it looks like there's heaps more room for front reduction, so I don't know why there's so little reduction done there. However I haven't sat done and worked out the torque/stresses going through everything...

I have started a new thread on for low range discussions rather than clog this locker thread with off topic information.
