Just because I already have one and it would save me changing to an R180R200, R200....why complicate and make expensive your life ?
I should have mentioned more - My car is a 78 260Z so has an R200 already (I also already have CV Shaft setup) and I am not planning on running stock power for very long. Cars use will mainly be road but I will also be attending the odd trackday and Drag race.For what it's worth I think Ian is going for 500bhp if I remember correctly
I don't think I'll ever be running 500HP. I still plan to swap in an RB as long as I can bring myself to take out the L26. If I go RB I am looking to run around 400HP, it will be fast enouth but I'll be able to use smaller turbos and tune for no lag and good response rather than outright power.
Would be good however if whatever I go with is also capable with 500HP just incase ever wish to run more in the future.
That looks nice and it is a good price but of course I'd also have to buy all the parts needed to change to R180 on top of that. Also the ratio is a bit low.He means one like this works a treat NEW 3.545:1 Subaru Impreza STI rear mechanical Limited Slip Diff R180 27011AB100 | eBay
Why not go for the Quaife in the first place? Road and track friendly, proven to do the bussines by memebers on here. If your not running stupid horespower the quaife is available for a R180 also.
I have a Quaife in my EF and its great in that (Imo perfect for FWD's) and they are definitly strong so I'd not have to worry about breaking it but the cons I can see are; its only a 1 way so I don't get the benifits of a 1.5 way (or 2way) and also the fact that it will behave as an open diff if one of the rear wheels lifts in a corner (although thats probably not that likely to happen) Most of what I have heard for performance driving is saying that CLSD's are far better.As Matt says, you can't do better than the Quaife - we have fitted several and the Owners have always been very happy with their performance and we've never heard of them failing.
So why buy anything else ?
I know CLSD's can be a bit snatchy but I've driven a fair bit in my mates GTST with a nismo 2 way and its only bad at very slow speeds and mini roundabouts etc but gives loads of grip in the corners and most of the time you don't notice ant extra noise or harshness.
I have an idea of the pros and cons of each but if anyone wants to add anything to this effect thats also good.Perhaps because Ian wants to hear the pros and cons for each application although I suspect a Quaife will fulfill his modest needs.
If my car was just for relaxed to spirited road use then I'd definitly go for the Quaife but form reports I've heard it isn't superior for performance driving, rather CLSD's are superior for this. While it (Quaife) might always be engaged to some extent they never lock fully, not sure that this is a downside though.I have run both CLSD and Quaife and for road/track the Quaife is far superior, no heat, no clutch plates to wear, always engaged, almost unbreakable, (I've missed 4th and hit 2nd buzzing the engine to well over 9K busting the solid diff mount.....phoned Quaife because I thought I had broken the diff and they laughed), diff has been in use for 7 years now.
Hard choice without try out both in a back to back test.
