Hi all i'm hoping to take the escos down the strip on sunday, But not sure if i should raise the back of my car as its on it's arse and therefore doesn't have much travel. Also should i stiffen or slacken the front at all. What about tyre pressures harder on the front softer on the rear? It's 2wd and i'm new to this drag stuff lol

i'd soften and raise the back end up, pretty much leave the front, and if you have access to blow them back up again, run the rear tyres pretty low (12psi sort of area)

Thats my thinking, i am no pro though, so im sure there will be people offering better advise!

 

Thats what i thought mate its running 235/40/18 888s so will hopefully grip

 

Soften both front and rear, to help the suspension react as quickly as possible and get weight transfer to the rear. I wouldnt raise the rear, as it will hinder weight transfer...

 

raise the rear so its got more squat before it goes into massive negative camber, raise it to the point its at almost positive camber, the it wants to be really stiff with low pressure tyres

and the front wants to be slightly lower than the back, and as hard as itll go so the front doesnt dip down between gear changes.

all imo of course, thats just what i would imagine to be good

 

If you stiffen it, it will make hinder weight transfer, and weight transfer is key to a good launch.

Soften both, and it will let the rear squat and the front raise, getting more weight on the rear tyres.

Raising the rear will mean it wont squat as much and you wont get as much weight on to the rear tyres. Keep it low.

 

but with a cossie they gain alot of camber as they squat, and this is not good for the launch. im sure more of the tyre in contact with the floor would give a better launch than more weight over the rear, and itll stiff squat and keep the weight distribution right for the launch if the front is as high as itll go.

then itll be nose up so more weight will be on the rear

 

Running low tyre pressure allows for the tyre to mould to the ground, so eliminating the camber issue.

Having things soft allows a quicker reaction, so getting the maximum amount of transfer.

 

Should grip alright with them!

 

What power is the car running? Its an RWD converted Escort Cossie yea??

To be honest, with 888s... softening the tyres up slightly and making sure that you do as much as possible to stop the rear squatting really hard on the launch should do the trick unless you're running serious power.

Throw a picture of the car up so we can see exactly how low we're talking here??

But then you can't expect old skool suspension design to cope with 400+ when it was designed with 220ish in mind, back in the 80s/90s.

Only 360 i have raised the back to a sensible height now sorry no pics before or after. It feels alot better to drive now anyway.

 

I certainly wouldnt run a 35 profile 18" tyre at 12psi.

I fact, I wouldnt even consider less than 20psi. Its not as if they are drag tyres, they are track tyres with a rock solid sidewall. Run them at a sensible pressure, not a dangerous one.

 

Good point, didn't notice the profile, i wont even let my 35's down, 30psi always, even slightly low and you run them flat!
