EVO STRENGHTENING COLLAR
Here is the latest version of my gearbox strengthening collar. It has taken a while and slowed down my rebuild but it is ready now. There are many bits involved and companies are not very fast when doing small batches ,especially prototypes. The collar is based on my previous one, but as some members showed concerns on how it would help with the case being broken by the final drive pushing on the case, I modified it and many parts have been added. The brace fits with no mods , no clearance issues with the chassis and can even be fitted without welding it to the case as the brace is very very well shaped with minimal clearance. This means it can even be fitted without dropping the engine and box, you will just need to lower it a little bit. The plate is secured by 4x10mm 10.9 studs to the bottom of the casing. To do so we have realized some simple but special steel screws : male side is 8x1,25 , female side is 10x1. These have been machined with high grade steel. A set of 4 alloy (6061)spacers are supplied and are used to correctly space the collar. As you can see a portion of the collar is skimmed. This is needed to clear the chassis, but it is still 10mm thick, so strength is not a concern. To finally stop the pressure caused by the final drive on the case there is a 15mm top cover, correctly shaped and spaced and two 10mm thick alloy discs that fit just over the bearings location. The alloy discs can be adjusted by 8mm Allen screws and then secured by bolts. In that way the pressure exerted by the discs is completely adjustable as you don’t want too much force to be applied there. Each disc has 4 screws on it, so pressure can be evenly distributed.(not pictured) I think this is as far as we can go with the std case. I know that some people will complain that the other portion of the case will now receive all the pressure, but I doubt there is something that can be done there, and I think the brace will really help a lot. Considering that a friend’s car has done many passes on the std collar and over 400bhp without failure, I am confident this new version will give even better results. All the parts are precisely cut and machined from high grade alloy and steel for a hassle free installation and performance. Depending on the interest kit can be realized in small batches. Please note that the kits will be made to order, with a lead time of around 2 weeks and a deposit is needed before starting production.

Put your names down iif you after one
Please cconfirm if you are after one as i am sending my order out
Yes, please.
Thanks for the heads up about the Evo collar being available now and as I mentioned in the earlier collar thread I'd like to get the Evo.
Just contact me by PM for the details.
GB ends tonight. Please hurry up if you are after a brace. This is probably the last chance to grab one as i don't know if a second batch will ever be made.
str motorsport...... i know GB has ended for this, but is there anyway i can still get my hands on one of these Evo Strengthening collars?
Thanks

str_motorsport will be doing a second batch of collars as announced yesterday on another forum "nissangtir" from the UK. You'll find it in the Performance mods section listed as "gearbox case collar 2nd batch" or I'm sure str will be listing that information here as well. The cost has gone up a little as with anything in this world now that a run has been produced and costs have reared their ugly little heads.
Your lucky as there was a time when he decided not to run another batch of collars due to the group buy stresses. There are also updated photos of the last revisions to the kit which give it more strength and even pressure to the end of the bearings (just a more refined product)
Cheers
Yes aa new small batch should be made.
As for cost it is a little higher cause we added some maching here and there for a better product.the previous batch is exactly the same design,but we have to involve 3 companies looking for the best bang for buck,but this is too much hassle for me,so we decided to involve oonly 2 companies to do all the work,but it is a little more expensive.
Ivan,your plate leaves on Friday
Excellent, thanks for the replys..... When can i confirm my order? How long before 2nd batch goes ahead?
Thanks
