I've been fabricating brackets to attach the front mounts for my 4-link, i've tried to judge where the forces will be applied and put metal in the necessary places. It's all square and straight and parallel within a millimetre or so.

What do ya reckon- will it twist/ tear off/ foul-up the handling or work ok?
Is it over/ under- engineered?
Is it damn ugly or does it fit in with the lines of the existing chassis rails?

Be honest- i can take it

oh.... yes i know i'll need to bash the floorpans a bit more

Unless you have diagonal bars linking the corners of the car you are always going to have chassis twist. I would bet that is going to be a lot stiffer than the original setup though.

Agree you need a panhard type rod to stop axle moving side to side adjustable one would be better than fixed type

Nice work DB.

i agree , you do need some form of lateral location to stop side to side movement, most comon is a single diagonal link on the lower arm, you could go for a sliding locator (like the big boys run ) or a watts linkage (like some astons run) or a panard rod (the easy way) whatever you do do something. apart from that it looks like a super job, you can put too much strength in a street car suspension but many people dont put enough. too much is better than not enough

Thanks chaps, guess what todays job is

Nice rocking horse

I have a cage which is goes thru to the frame rails, should do the trick?

Gettin a bit threadbare now- luckily i've grown too big for it anyway

YAAY
Panhard rod installed, shock mounts and anti-roll bar next

WHY DID I GET AN ANTI-ROLL BAR

Now i've installed the 4-link & Panhard, i can't see how the car can possibly roll on the axle cos the 4-link holds the 2 parallel (ish), i can't see any possible need for the a.r.b.

SECOND PROBLEM- i forgot to check Panhard clearance on full axle travel and they collide
DO I - Bend the Panhard (with a proper pipe-bender) in line with travel so the rod ends don't get out of line.
OR - redrill the chassis mount and extend the axle mount to raise the Rod higher.

Great work db! Fancy fitting me frame connectors??? God, I'm a lazy get!

Bend the panhard - job done! Also, I would have thought radius arms would have done the job, too.

I'm a bit suspicious of panhard rods. OK for cars with tight suspension with little movement (Caterams?) but I would have thought that the arc they travel through when getting angry with the car would cause a bit of side-to-side wobble???

Hell, what do I know - I'm drinking beer!!!

Cheers Philth!
I figured bending the rod would be ok but it's the sort o thing you want a 2nd opinion on
It's pretty much a mild pro-street car with 18" rear MT's and skinny fronts under an all steel B bod-- i don't think i'll be gettin angry round any corners! Not on purpose anyhow

P, can you re-bracket the panhard to the inside of the frame section rather than underside?
