What spring rates are you using, the camber change looks a bit excessive, perhaps the spring rate is a bit soft. What is the toe, too much toe, in or out will wear the inside tyre as will excessive camber.

This might be of interest as well. https://www.youtube.com/watch?v=GuI0hH2TuxQ

This is a good view of what happens with out of alignment tail shafts and velocity.

Hi Luke, Just let me know a price for post to Queensland 4575. Thanks Dave.

Hi Luke, Could i ask you get a postage cost to ship to me in Queensland Australia? I understand completely if you don't wish to post O/S. The trouble with postage costs these days is it make things way to dear through some of the major companies. Maybe Royal Mail via the local Post Office. Cheers Dave

I am a cheapskate, i made my own using an oil filled gauge. 0 to 35 PSI for the Caterham and i have one for my off road race buggy 0 to 10 PSI. I couldn't see the need to go higher than 35 PSI for the Caterham and the lower the gauge scale the easier it is to read. I run mostly 18 - 20 PSI for the Caterham.

Thanks Shaun, I do have the Bosch green giants but they won't fit if i move the injectors to the ITB's. It looks like i might need another fuel rail as well.

Can someone please let me know the part numbers for ITB mounted fuel injectors and fuel rail for use with the flat back air filter. I'm guessing either 250cc or 330cc injectors.

Is there an advantage to placing the injectors in the ITB's over the standard head location?

I think you're right there 7 wonders and the problem was exacerbated by the carbon plates wearing so fast that the Belleville washers had to go way over centre to apply pressure to what was left of the friction clutch plates which makes them crack then break up.

The O. S. Giken Diff. https://www.difflab.com.au/pages/os-giken-superlock-technology I would be very interested in others thoughts on this diff for a Caterham.

I got some quotes to rebuild the Titan here, labour alone was $1500 - $2000 if all went well. I wanted to supply the parts but was told they wouldn't guarantee the work unless they supplied the parts. The decider for me was that no one here knows what a Caterham is, yes they can rebuild a diff but i wanted someone that knew the quirks of the Caterham. I did a lot of reading about the different options for my car and after several emails and phone calls with Ollie at RRT i went with the Drexler. Another diff i was really interested in was the O.S Giken made in Japan i think. This would have been my first choice but the OS Giken dealer here just wasn't interested in me at all, too busy with racing cars apparently. I did get on to a company that sells the O.S Giken in Italy of all places and the manager there was so helpful, he contacted the factory for me and was told they had made diff centres for the BMW 168? case in the past but none were available at that time but they were looking into making more in the future. The O.S. Giken diff from memory uses coil springs as well, not Belleville washers. I think Belleville washers are a weak link so coil springs are appealing to me. My other car is a Leyland Moke and they use a large Belleville washer as a clutch spring and are a pain to set up properly to get them dead flat.

Personally the reason i went with the Drexler is because i don't want to be pulling the diff out every couple of years for a rebuild. Ollie at RRT believes they are the strongest longest lasting option for me. I also considered the Wavetrac for the same reason, low/no maintenance other than oil changes. I am considering sending my RS Titan LSD back to the UK for a rebuild by either Tracsport or RRT and that will be based solely on cost because it will be a spare that can be put back in when/if i sell this Caterham and get another.

I hope this comes out ok, It should be an explanation of the Wavetrac and why it seems like the best of the ATB diff centers.

Doc, that price included sending the diff to me in Australia, postage is not cheap!
