A Weird Qtr Mile Idea

[cybernck 402 1 Cars]

as we all know, RWD is so much better for starts than FWD due to weight transfer and loss of grip.

 

 

so, what would happen if you'd replace front shocks/springs and rear shocks with rigid bars/tubes

so that there is no suspension (meaning almost no weight transfer possibility).

 

it would be too dangerous if the drag strip is bumpy, but not too much with only rear rigid suspension.

 

 

also, having the rear end raised some 5-10 cm's and front end lowered would help further more i reckon.

 

 

one would obviously done this mods in situ only for the drag run.

 

 

discuss!

I dont think it would be good to have rigid front suspension as the shock absorber keeps the wheel in contact with the ground therefore improving traction, but a solid rear end would do a lot for weight transfer I would say.

My car has such an immense amount of torque & my Quaife ATB is so damn good at transmitting drive,that with the correct launch approach,I now end up spinning the planet beneath me. I can now go from one time zone to another in 10.2 seconds.

Too much of this behaviour really does annoy the Americans though. They do like their sleep.

lower BOTH front and rear, as this would reduce weight transfer (since the shocks are strained) the problem with FWD also comes from the rear shocks, if you got solid front shocks but soft rears, weight transfer would still happen.

 

Simple ideas to get a better time....... these mods can be done without too much hassle:-

 

use the tinest tyres possible for the rear, 145 section rims and tyres or smaller! (if possible) these will have less friction and you will gain a bit of topspeed.

 

lower the car as much as possible, better aerodynamics and less weight transfer

 

if you got a problem with high gearing get smaller radius front tyres, and if possible use steel wheels as they are lighter, something stupid like 195/45 /14's for example with a grippy compound.

 

remove as much weight as possible, no spare wheels, remove as much off the interior as possible.

 

in extreme, use tape to cover lines....... like between the bonnet and wings etc.. (may sound stupid, but it helps aerodynamics)

But you will still get weight transfer though won't you?? Just becasue you can't see it happening doesn't mean it isn't, it might be reduced but I would have though thatas you aceelerated the weight is still transfered to the back somewhat.

[speedy 2]

you will always get weight transfered.......... the trick is to reduce it.

speedy> what do you think of solid rear shocks idea then?

 

 

c_w> will your feet get up in the air with a solid chair as much as they'd go up with a swinging one?

I saw a R5 GTT runing solid rear shocks in an old mag - with the rear end raised a couple of inches as well - was putting in some of the best 1/4 mile times.

Raising the rear should also increase traction as more weight is over the front wheels.

[cybernck 402 1 Cars]

yeah, that's why i mentioned those two ideas.

 

happy to see it was used and successfully on top of that .

 

i will definately have to try it.

 

thanks.

I think running a solid link instaed of a shocks on the rear and having it raised is classed as the norm on drag racing front wheel drive cars,but I wouldn't like to guess how much quicker it would make you.

If you look at drag cars the fwd ones they are jacked up at the rear and running really wide rubber up front. Theres a focus running something like 10's or less (its a space frame with focus esque fibreglass shell). I know this sounds stupid but doing something like putting lead weights in the engine bay will help lower your quarter mile times. More weight over the driven wheels is better.

 

Running smaller dia. tyres will give you better acceleration but limit your top speed, what you really want is lots of rubber on the track with a large dia. etc.

cybernck >>> a solid chassis is always better for the dragstrip, that is why dragsters do not have any shocks.

 

I was talking about improving your times with your ROAD car, which will always be harder once you do use that car to get to and from the dragstrip.

 

but yes your idea is used on non road cars.

 

DrSeuss>> as above..... having a dragster is one thing , having a road car is another. Weight is never good altough i get your point regarding grip.
