If you was to graft a new rear beam on to a cossie' What would you use ie' to accommodate wider back wheels and in terms of adjustment of suspension etc ? Mustang / 200sx / GTR ?

Please discuss

 

I wonder if sommot like a modern bmw rear set up would work? Mainly made of alloy so its light, and i'd assume to have plenty of adjustments?

 

Keep thinking about something like this to accommodate a good suspension set up

 

Just looking at this http://cgi.ebay.co.uk/SKYLINE-GTR-R3...ayphotohosting

 

The rear beam to go for is an Ahmed Bayjoo jobbie gonna throw one in my car next year

*EDIT* Thats never happend before lol.

But what if i want to fit some wide tyre's? Not going to get more than 215's with the standerd beam ?

 

See above post

doug what you thinking of now man!!!you only just got her running

 

Hey Doug


Well i want to get it painted over winter and just toying with ideas' So why not cut it up to fit a PROPER rear end

 

hey dont put him off...he's willing to try sommot to save me the aggro of trying it first

Would be interesting to see what could be made to fit tho...plenty of cars out there to go round with a tape measure to quickly size up whats possible.

 

1 thing i have never heard about a saph is that they are good handling cars without adjustable rear beams etc.is that true?i have coilovers on my 2wd and proper poly bushes,its been cornerweighted but the damping has never been set.i think its ok,but that rear beam weighs loads and its basically the same as any other sierra,and when it travels up the wheels gain camber,that cant be a good thing!

 

^^ Hence why 2wd cossie's put out shite quarter mile times for their given power output.

 

i feel a bajoo beam will be fine doug!!!!was you at ND?

 

Exactly that mate' Yes it would be a lot of work but i recon it would be worth it' Just imagine some 255 / 265 Rears on a cos

Not at ND this year Doug but defo going next year

 

Anyone got any thoughts ?

 

I'd use a BMW beam.

 

what one and why Rad ?

 

2.8 capri atlas
back in the day most of the top thunder saloons ran them

 

I was going to use a 325i beam in my S2 with an M3 diff. Strong, and a small beam, so lightweight.

 

Thats why BMW was the first to spring to my mind. Think the best bet would be to go to a local scrappy with a tape measure.
I dont think you'd gain owt in tyre width tho tbh....imo thats limited by the actual body and I dont think you get massive gains over 245 anyhows...go to far and you'll over shod it. Its the actual camber angle change that needs addressing more than tyre width.

 

Like this ?





What is it that actualy makes cosies squat ?

 

The spring is close to the inner hinge point of the suspension arm, making forces that act on the suspension "strong". Force x Arm = Momentum or something like that. Just a wild guess though.

 

weight transfer makes them squat. Can be helped by increasing the damping on the rear shocks but that is just reducing suspension travel making it skitish.

unequal length arms make causes camber change and bumpsteer. Again limiting travel will stop it but causes the above.

I think every 2wd cossie would benifit from an uprated diff, transforms the handling IME

 

You might find the 300ZX rear end as an option, the diffs are strong and are used in a number of cross breeds here.... They are reasonably priced too.
My wife has one and they have loads of good stuff on them.

 

also on the jap side....what about a GTS Skyline arse end?

 

Think i will have a look at my bro in laws one in the next few days

but you could get one for cheep too' and im sure they take loads of abuse.

 

What do the RWD skyline boys do for uprated diffs? Anyone know, Maybe Steve (Stav) should be pointed in this thread direction...

 

I have an ATB in mine at the moment and i know there is better diff's out there but its more the geometry i think that needs to be sorted

 

GTS and GTR Skyline are the same, apart from the hubs. GTR's are wider and made of alloy.

There is a Sierra XR4ti in the USA with a Supra rear end fitted in. Have a search on google

 

You got a link anywhere? had a quick search but couldn't find anything.


Any more imput ?

 

Me n Mr C was talkin bout this the other day when workin on a friends 200sx, it looks like it could b a easy enough swap, the diffs will take a easy 400 bhp all day long n just for good measure they throw in oil coolers as standard

and the settings and addjustments that can be made is endless

 

Didnt take any pics did you

 

No sorry, although i will b popin over next weekend will take the cam,

 

I've got some pictures of 200sx's rear beams, Give me a sec will get them!

 

Here you go

 

nice 1 fella,

it wont b a simple job fittin 1 but its gotta b cheaper than a group A rear beam with shed loads more adjustment, and its nissan so the parts wont have fookin cosworth tax added on

 

Nice one radders .. Thanks

 

that looks easy.

How much would that 200sx rear end go for? I've got a P100 sat waiting for a rear end

 

Not sure, But you can pick up S13's for peanuts these days, So i'm guessing fairly cheap!

Not sure what the parts cost, but there made by K-sport, Which have had a good feedback on quality etc.
