Limited Slip Differential (LSD)?
I'm quite keen on fitting a limited slip differential to the back of the Tiger Avon. For obvious reasons, I want to reduce wheel spin, and tank slapping moments in the corners. However it doesn't seem quite as straightforward as it sounds.
Avon Mountings?
The Tiger Avon chassis is designed around the 7 inch open differential with push on drive shafts, typically found on most sierra's. I happen to have lying around a Sierra XR4x4, with a very good 3.62 Limited slip differential, naturally I wanted to use it as it would save me money in the long run.
However after a conversation with Tiger technical support, it seems as though quite a bit of work may be required to fit one to an Avon. Firstly the chassis mounting would have to be modified to take a 7.5 inch differential which is fairly prohibitive. They did tell me that a certain number of 7 inch LSD's were manufactured but these seemed quite rare. My best bet would be fitting a Quaife custom LSD. This would cost around £600.
Also another issue would be the size of the hub carrier. This would have to be machined out to accept the wider bolt on style shafts. This could be done relatively easily, probably by Tiger themselves.
Living with an LSD
LSD's may be great on track, but what are they like to live with. Well I hadn't really thought about it until I started researching more. An article from the Tiger Owners Club forums seems to suggest that handling in everyday trim might be impaired. The major complaints were a general lack of feel from the car, less warning when the back was about to step out and an inability to get the power down with out the back end of the car squirming.
The article related to LSD's fitted to Tiger CAT's which feature the full sierra rear axle. It would be interesting to see if the characteristics of the Avon with its full independent rear suspension, would cope any better.
