ek9 turbo build


Managed to completely deform one of the new bushes whilst trying to fit it to the front lca today, i left the bushes in the freezer over night and heated the arms up to 50c, thought i was onto a winner when the first one went in easy, the second bush was a bit harder to get in then boom the socket i was in using in the vice slipped and wrecked the bush! Need to order a new one.

Also i didn't realise that the d2 rear lca bushes are a different size to oem/ hardrace (after annihilating them taking them out) so the hardrace bushes dont fit and one of the arms doesn't have any bushes in it !! :(

One of those days were you try to get stuff done and it all goes wrong, not quite sure what to do with these arms/ bushes.
 
I used a socket and a hammer to get hardrace bushes in before.
 
I tried that but they wouldn't budge, did you fit new rear trailing arm bushes to yours? Ive not tried yet but they look difficult being so big and having the mounting points through the middle of them.
 
Il give that a try then lol, i feel like torching this damn car!

Maybe the seller might take back the rear lca bushes in exchange for a discounted pair of hardrace lcas.
 
With abit of luck yeah.
If not then sell them on here. I'll be after some hardrace bushes in the near future. Can't afford anything atm though.
 
Il see what they say, but if they wont il hold onto them for a bit for you.

Another thing ive noticed is that the springs on this car are 200lbs rear and 375lbs front, that doesn't sound right to me.
I know its a different car but my dad runs 600lbs rear and 450lbs front on his alfasud race car, it just seems way soft or maybe these gaz ghas are more of a road setup?

Could i up the spring rates on these dampers, are they likely to handle an increase in spring rate?
 
Had to convert into kg/mm for me to understand how much that is lol
Yeah does seem abit too soft. Esp for a race setup.
I worked the fronts out to 6.6kg/mm I'd be wanting more like 12kg/mm so I'm not sure the damper would handle nearly double the spring rate without some valve work being done?
Iirc gaz are rebuildable so could get them revalved to suit stiffer springs?
 
Do you run the rear stiffer than the front? Im not sure if there rebuildable, they might be but there only the ghas not the golds so not sure.

Tbh the suspension on this car looked like it had been pulled out of the sea lol, not sure weather to just save up for new dampers etc.
 
Not on these I wouldnt. On the ep3/dc5 it seems beneficial to go harder on the rear but not on these, I believe it has something to do with wheel ratios and there is a way to work it out but it's above me tbh lol
Most Coilovers seem to run 2kg/mm less on the rear than the front our cars. You'd hope atleast one of them did abit of research.
 
That's something I didn't know, I was always under the impression that Fwd cars are better suited to having the rear stiffer!

Thanks for that, that's actually quite interesting
 
The weight the rear springs have to hold is much less on the rear than the front so less spring rate needed to make it "stiff"
ARBs have an effect here aswell.
It's really complicated from the books I've read and no perfect setup for every track. Trial and error is probably about as good as people like ourselves could manage.
 
Wheel frequency was the term I was looking for, not ratio
 
When you installed your rear trailing arm bushes how did you make sure that they went in completely true so that the mounting flange that goes through the centre of the bush sits flat to were it bolts to the car?
 
Used a tape measure on the old bush so I knew how far "in" it was mounted.
On a lowered car it's probably best to set the bush in at an angle so the bush isn't twisted when it's all bolted up and on its wheels.
 
Another thing I didn't do then!

I just took the bushes out without measuring so I have no idea how far in there supposed to be.

Cheers for the advise on turning the bushes a bit :)

I've got a set of gaz coilovers here as well, with the same spring rate if I remember correct,

What I had thought about doing or at least trying as a temporary solution is swapping the front springs to the rear and buying something like 8.5kg springs for the front and see how it feels
So 8.5kg front 6.6kg rear
 
Would be similar to my cuscos then. Still abit soft for my liking but not at all bad.

That sounds like a good idea, better than how it is atm any way lol. Do you know were to get good springs from?

Jesse, can you remember how far in your rta bushes were sitting when you measured them, i did read somewere that its about 12mm?
 
Sorry I can't remember. The old bushes should have some damage on them so could be worth checking them?
