Diff lock wont change your geometery but you wont like it so don't bother..........
Just remember what I said about the clutch

 

Hmmm......Im confused.com....again!
What about subframe lock?!!

 

It will provide a lot more feedback, including vibration, from the rear diff. You can just fit the bushes and not the bolts for some reduction in flex from the diff carrier.

 

Subframe Lock Kit just pins the rear subframe to the body, eliminating any flex in the subframe's rubber mounting bushes - Also ensures the subframe has a zero thrust angle (ie sitting straight on the car) - If your subframe is not aligned straight, you may find that you need to loosen the subframe in order to be able to fit the locking bolts - You would need to have the car re-aligned, as you will have altered rear camber and toe settings. - Some of the classic STi RA's had solidly mounted rear subframes, so no need for a lock kit if you buy one of these

Diff Lock kit just stops the T-Bar diff carrier from twisting and banging on hard launches/shifts.

I fitted both to our blue classic, and didn't really notice any more noise or vibration, but that's probably 'cos the exhaust is so fookin loud

 

Thanks for info Rich.
Il buy the kit off Guv & just fit the diff kit bushes for the moment.
At higher speeds & high revs, when comming off the gas abruptly I get an occasional sound of,- I think the propshaft thudding into underside of body or subframe. If I come off the gas smoothly then its fine.

 

Can we watch

 

Should I help with the fitting?

 

Someone should, or else we'll be redressing the threads. The bushes are quite easy, I did my own, but spanners and socket sets can be a challenge for Ricky

 

Yeah anyone else apart from John & Rich, want a tutorial workshop from me on how to fit the diff lock kit then I would be happy to put your names down too

 

More than likely, it's the diff carrier banging in it's mounts - Diff lock will eliminate this, as it just packs out the freeplay in the standard bushes.

 

I'll look forward to it

 

Il give you spanners & sockets!!

 

I'm spectating - I'll just bring a chair and a flask of Tea, no tools

 

I'd bring a sleeping bag

 

Dont you two have any work to do or sumit!!!

 

I'll get the popcorn

 

I'll bring the barbeque ..... whos bringing the beer?????

 

That's not what I heard about Ricky's mechanical expertise...

(Sorry mate, couldn't resist!)

 

I can bring some beer, and once we have had a few we can sort out whatever mess Ricky makes, oh and yes - I'm in work

We shouldn't let Ricky have any beer though as he'll lose his scarf

 

This is what happens when you get free internet on your new phone John, start using it when your meant to be working! You'l end up leaving your soldering iron in the aircrafts jet engine if your not careful!!! lol

 

That's why I'm in IT and sit in front of a computer all day

 

Wat no soldering iron & jet engines !! lol

 

I have a man for that

Packing up ready for an office move, which means a nice long weekend to get some bits started on the car

 

Let me know, Il give you a hand/advice/expertise.

Failing that,..................tea/coffee!!

 

Coffee, white none

I'm off Monday and Tuesday but I have a load of stuff to do around the house as well as some training so the car may just have to wait (plus I'm waiting on some stuff)

 

Sat morning gona give the backbox & tighten up & mid section.
Also going to check the preload on the rear shocks & tighten up top collars to increase preload Im thinking. Does pre load have to be exactly same on left & right shock? Its just that I think off side rear needs more preload than nearside rear.

 

As I was saying when my other phone rang, I don't think its worth the effort on the exhaust until you get a flex joint in the system. Every time you boot it, it will shift again and it will be a never ending task. You need to get something like this in and get it welded in place

just leave it alone lol

 

What's the point in having it if you can't break it

 

Depends on how much petrol you've got in there but doubt it matters with a Spec C tank! Why don't you take it to get corner-weighted if you want to get really fussy?
