help needed KE25 weight

[rob20v]

Can anyone please help me with KE25 vehicle weight. I know the total weight but would like to know what the break up is from front and rear or even better if I can get individual corner weights. I have searched for around but with no luck. I am trying to sort out the correct spring rates before I purchase the springs for my coil over setup. I have decided on a set from Peders as they can supply all I need at a reasonable price. Threads retainers for $260 and springs for $180 a pair.

for a dead stock car or modified?
can you put in a set of random springs, then fill up with fluids and yourself, and get corner weighted?

Just to give you a rough idea, my KE25 was corner weighted and the front suspension supplied/setup accordingly by apparently a guy who knows his stuff (at the time he was setting up a few Porsche Cup cars etc which I think he still does??) and it has 200lb Eibach springs up front with Bilstein shock absorbers re-vavled to what he specified.

It seems to work quite well, quite "stiff" on the street though, great when pushed hard and on the track.

NB. The rear also runs Bilstein shock absorbers, the rear leaves were reset and an extra leaf added.

hey i heard you can go to certain suspension places and they have a machine that
the car sits on and it weighs all 4 wheels so you can fine tune suspension and get weight distribution figures for adjusting the weight more evenly later on front/rear and left/right etc...

i think you need your car with you in it and its particular mods to get an accurate reading
as everyones car will be different, especially the more modified it is eg: engine conversion
or diff conversion.

maybe fulcrum suspension?

I just want to know the weight for a standard KE25 as they were released.

[styler]

well qld code of practice of light motor vehicles states 756kg

[oldcorollas]

front rear is something vague like 55/45?

easiest way would be for you to hire some corner-weight scales, and do it yourself... even if you are just propping it on the scales with bits of wood under the wheel positions

54.5 front weight according to here

Sooo you know or you don't????


My old rego papers stated the standard KE25 weighed 780kg

Look on the net using google and there is actually a method for calculating corner weights using a tyre pressure gauge, some A4 paper, a ruler and a calculator.....and some maffamatics .

But yeah, unless you live in the middle of nowhere just visit a performance suspension workshop and get it corner weighted or almost as good just go to your local tip and weigh the front on their scales then the rear.

If what a lot of suspension people say is true the springs from pedders (and many other places) will be lucky to be the stated spring rate you order anyway so it'll make your corner weighting accuaracy negligible.

Thanks for the help. I know the aftermarket springs can vary in what they are stated to be but if I can get it close at least the car will be somewhere around where I want it.

You should get pretty close to what you want for sure.

Out of interest, what have you got planned for the rear end in terms of suspension??

[rob20v]

The front end will be nissan R31 struts and standard R31 brakes with pedders springs and adjustable spring seats, the rear will remain the leaf springs with some fine tuning with a TA22 3.9 beam rear axle with the standard TA22 drums. I am still trying to work out a few things to see if I need adjustable top hats.Work in progress. Any sugestions could be helpful. I currently have 13 inch performance superlites which will be sold to finance a set of 15 inch wheels the same.

[YLD-16L]

15" wheels are a good choice for the KE25 Rob, a great variety of tyres available in both budget and performance and they will sit nicely in the guards without any mods to the guards..

I think Bananaman is using R31 struts in his CA18 turbo powered KE20, he went for the option of adjustable strut tops from T3 - I think he worked out they were necessary for attaining the camber settings he was after.

For strut tops the T3 and Noltec ones appear to be the pick of the bunch.

Replace all your suspension and steering bushes front and rear (if they are old) and if any of your ball joints or tie rods are in need of replacement just do them all at once. If you only replace the dead ones the others will have a funny tendency to die shortly after

It'll probably be best to get your front end setup and then setup the rear to compliment it as leaves won't give you a lot of room to play with in terms of adjustment.

I Have a set of 17 inch wheels but they look like monsters under the KE25 guards and would probably hit. The R31 (Nissan in general) are the only struts which line so I can still use the original KE25 balljoint mounts and lower arms without doing a cut and shut which I don't want to do. I have made adaptors so can still utilize the dowels on the lower arms and adapt them to the nissan struts.

[YLD-16L]

I have 16x7" on mine and I'd prefer 15's so I have a better range of tyres to choose from. Anything too tall in profile would rub, my guards are lipped front and rear and the front guard are widened too. 17's would need a pretty damn low profile tyre too I would imagine.

The Nissan strut does seem like the best swap for the KE20/25 that's for sure. Opens up an easy path to bigger Nissan 4 pot brakes too.

Thats correct. I did measure the KPI angle, and got 9 deg on stock strut and 10 deg on the R31, so you have 1 degree negative to dial in to get it back to factory. I Don't want to run anything crazy, but i want the flexibility to toy with it if i want. The T3 tops seem like they'll deliver this with some fiddling.

Oh the other thing re the R31 struts, as i'm sure you noticed they won't accommodate the locating dowels on the KE steering arm. Rather than losing the dowels and that added shear strength, i had the threads of the struts drilled out a little and made the dowels a smidge shorter to accommodate for them. If it was necessary i was going to run a nut on top of this, but there is enough thread left in the strut for it to not be an issue.
