Plates were not carbon and according to R&R were in perfect condition - just my Belleville springs needed replacing - R&R say my rebuilt Titan LSD is as good as new! Will probably be trying to sell it soon! My Titan LSD had always been quiet (I started with an open diff and had the LSD fitted after about 5 years of ownership so I could do donuts giving joy rides at the Children's Trust Super Car event! - did not notice any significant noise change when the LSD went in) so when I started to hear loud clonking noises when turning at low speed I knew something had changed. Do not really understand why there should be any noise difference between different plates types (be good to have some wisdom here!) I presume when they are fully engaged (therefore all spinning together) there should be no noise generated from the plates, but perhaps when they are 'disengaged' (therefore 'clutch plates' spinning at a different speed to the 'friction plates') there is still contact due to the pre-load which means different materials could make different noises? Surely they should not be 'rubbing' too much when not 'engaged' as this would result in rapid wear and lots of heat? Have done a couple of short rides with the new Tracsport LSD fitted and diff back to nice and quiet (relatively speaking) again! Difficult to say how long the Titan will last - R&R said I was lucky to get 4 years out of mine - I think the issue is more with the springs than the plates although as said earlier the Titan plates have to work much harder than the Tracsport ones due to their smaller size. Seems odd to me that we should expect to have our LSD's out regularly for a service - do not lots of performance road cars run plate LSD's and one does not hear of them having to come out regularly? If you send me your email address I will send you the pics of the different sized plates and ramp blocks - tried to post them here, but when I uploaded them they were converted into such small pics they were of no use!

This will not really help you if you have a BMW diff, but thought I wouild post anyway! My Titan lasted less than 4 years (and I am told that this was good going!) before it had to come out and have a rebuild (few track days and several road trips) - new Belleville springs required. Had a long chat to Steve Perks about the various designs etc (also looked at the various components at his workshop to compare his and Titan's) and persuaded his unit is better for three main reasons - larger friction plates able to cope better with the huge loads transmitted through the diff, Belleville springs are better quality and are not compressed fully in the Tracsport unit (as they evidently are in the Titan) which means they do not lose function and thirdly the ramp block walls are thicker meaning more surface area contact on the cross pins meaning less risk of steel fatigue and damage to the ramp blocks and pins! Have now fitted the Tracsport but not been able to drive much for reasons we all understand. Road and Race say the Titan diff will generally need to come out every few years for a rebuild (which is not too expensive if you are able to take the diff out yourself!) Steve Perks says his Tracsport unit should not need these regular rebuilds. Will have to report back in several years on that! As mentioned in a post above Palmer sports are now into their second season running Tracsports and no problems so far. I understand when they were running Titan diffs they were having to have them rebuilt once or twice a season! I understand that Tracsport offer a smaller range of ramp angles, but cannot really comment on that as I have not got to grips with understanding the implications of this!

Like the pic in post 4 but I used some old IKEA table legs I had knocking about with some pipe insulation

That too!

Thanks all - brakes done now and a short test run to check them! Also check that the new LSD diff was working! Car moved and went around corners so I guess it must be fine!!?

Many thanks

Planning on replacing brake fluid tomorrow. Have newish front calipers which I see have two bleed nipples one on either side of the caliper. Do I put pipes on each of them and bleed them at the same time? (bit tricky!?) Or do I do each side individually? Thanks Garth

For others reading this thread is it worth considering a Laminova oil cooler? Have one on my modified Sigma after having problems with soaring oil temperatures on track days. Oil temp now pegged much closer to the water temp and does not overheat when pushing on. Think I am right in saying it also heats up the oil slightly more quickly from startup which also has benefits? Trust this post is not out of order!

Thanks Nick - will have a look on Facebook - it is a fantastic car and in very good nick.

BTTT - any ideas on where best to try and sell this car?

Hope it is ok to post this here. My son's M5 is for sale, link to autotrader advert here. Fantastic car in very good condition. Previous owner was a good friend who only ever used it for long trips - my son has had it for about 18 months, but is now moving into Central London where it is impractical to have a car - selling reluctantly!

Sorry to hear you are having problems. Replaced my clutch slave on my sigma (with Alan!) 18 months ago - had problems getting the spacing correct, but there was no seal at the back of the CSC. How are you bleeding it? When mated to the engine? Perhaps if it is over extended it will leak from the back? From memory it is almost fully compressed in its 'static' position (ie clutch pedal out!). Good luck Garth

Have just sent you personal mail

Presume it is still under warranty?

I have not looked at the Tracsport, but might have when I had my Titan installed (it did not come up as an option!) - better look at what maintenance is required on my Titan then - have generally thought one just needs to make sure the oil is good and then diffs are pretty maintenance free!

AdamQ - interested you went for the Titan LSD and not the Tracsport one. I have not looked into the Tracsport myself, but '7 Wonders of the World' who posts on here thinks it is the much better engineered unit! Worth another look Ferrino?

I do have a vinyl one I could sell you £35 + postage. Am leaving for a road trip tomorrow for 3 weeks in Europe, so will only be able to deal with it on my return! Garth

Just seen your post - I think I have one stashed away - are you still looking?

I will have it thanks

No comments on the wheels yet - I would personally go for 13"!

Hi Stu Mail sent - let me know if you do not receive it. Garth

Bought this sub loom for my car (Caterham part number 76149) only to discover I had a pre-fitted one on the car already! Free + postage to a good car!

Look like 15's to me?

Got the pedal thanks Andrew
