I want LSD!!! (and I aint trippin')

I kno exactly what you mean mate. I suspect ill stick with whats simple and cheap for a bit, but I may end up yet with a 500 quid car with a 500 quid diff in it if it makes as much difference as I reckon it will!

I for one would happily spend £500 on a quaife. If we could get an order together for 10 then they'd make them for us. And we'd be laying the groundwork for future fast 300s.

How essential is it that the unit is an LSD, as I've heard some of the newer lockers aren't too bad, only problem is you have to be more comitted to a turn. (a powertrax lockright can be bought and shipped for ~£140 and should fit straight into a dana 30 diff)

Cheers

3 types im aware of

Quaiffe ATB, very soft, ideal for fast road, doent require rebuilds, not good for drifting

Gripper/other plate diff, require infrequent maintenance, lock better, tend to be more grabby than the atb, but ideal for drifting (what Id want)

Locker, like being able to change fro open to welded quickly, not suitable for road use, commonly found in 4x4s

I'm on about something like a powertrax lockright which would come under your "gripper" heading as it does allow gears to "overun" each other through corners.

If it does do what I understand it to do (someone should definitely look into it, but not one of my priorities), then one can be picked for £140 inc shipping from america off of an ebay.com shop

any links to info?

Post by **Jason B** » 12 Sep 2007 10:42 pm

Heres their site: http://www.powertrax.com/

and heres a guy who sells them on the bay: http://cgi.ebay.com/ebaymotors/ws/eBayI ... 71177&rd=1

Just noticed there are a couple of variations of the unit too, one may be useable. Give us a shout with anything you dig up as I am tempted to see whether one of these could be used for rallying.

Cheers

For gravel rallying either would work I suspect, you have enugh slip on a loose surface, and low speed manouvering noises wont bother you. They lock pretty much all the time, apart from round corners, whereas an LSD is open, till you spin one wheel from what I gather.

For a road car or tarmac rally car i reckon the synchro unit is better, but I dont know how harsh its action will be, it is a full locking differential (welded stylee) as opposed to a 45 or 60 percent locking clutch type.

What fitment do you need for a 360? I read earlier int he thread about the dana 30, but it wasnt a direct swap?

Post by **foggyjames** » 13 Sep 2007 12:13 am

The trouble is, a 360 diff isn't a Dana 30....it's something smaller and pretty much unique, as far as we can tell. 240s use a Dana 30 (and I assume 7/900s do too). Certainly, a good LSD from the US is a fairly cheap item for a 240.

I have a contact who will custom make you (on a one-off basis) a very nice agressive clutch LSD - nothing like the ATB. We *might* be able to negotiate a further discount if we can get a group buy together. I'd probably be up for that. When I asked Quaife, it was going to be £600 a pop for an ATB if we ordered 10. Bastards.

I agree that a true locker is a bit brutal for road use...the transitition to having a solid axle usually results in a spin, unless you're a genius driver...I don't think it's wise to unleash such a device on the public.

cheers

HeHe

keep us posted on any prices that get flung around for such "custom" units, but I am a student and suppose I best not spend too much of my loan on an lsd.

Lockers work perfectly fine on the streets..just a lot of chatter on very tight corners. No need to spread misinformation if everyone is just guessing. Offcourse a true LSD is better, but for price and reliability, the lockers are just unbeatable.

Post by **alistairolsen** » 14 Sep 2007 07:49 am

Damir, do you have a source of lockers to fit a 360 without modification?

Post by **Damir130** » 14 Sep 2007 08:16 am

Nopes, but 240LSDs have been fitted with minor modifications, so a locker will fit too. This has been discussed several times on the forums, including pictures of the mods needed.
You also have the dana30 true trac diffs, which are in essence a Torsen type differentials.
