Ke10 Suspension Setup

[Jono.C]

Hey all

 

In a matter of weeks i'll finally have a ke10 sitting in my backyard. :)

 

I've waiting 10 years and finally got one :)

 

 

I'd like some help/ advice regarding front end setup.

 

The ke will more than likely recieve a form of forced induction, more then likely 4agze

 

 

The help with this steering and stopping i thought up a setup (mind you this just in my head with no knowledge of what fits etc.)

 

 

Plan is ke20 engine cross member, ke20 lca's, ke30 struts and brakes for 4x114.3 convertion, ra40 tie rod ends, ke20 sway bar etc..

 

 

Now, i'm wondering does any see any problems with this setup? from a building or driving point of view? i don't have a problem with a track increase or mild camber addative.

 

But if anyone knows if any of that setup will/ wont fit any help is very greatfully appreciated, also alternate setups are welcomed.

 

 

Cheers, Jono :)

a easy upgrade (not for everyone though) is nissan silvia upgrade you get more camber (5 degrees I think) cheap coilovers, massive brake upgrade potential (skyline 4 piston calipers) but apparently it changes the steering geometry.

ahh 19914afc such an uneducated post:P

 

it does not "give" you 5 deg of camber, yes the s13 LCA's are long, but you use camber tops to adjust it to what you want. and you can use R31 arms to bring the arms closer to standard length (R31 arms are about as long as xt130 arms)

 

the "cheap" coilovers are usually far to stiff for any use in a corolla, and a ke10 is going to be the lightest of all of them, so you will be changing spring rates and more importantly shock valve rates in order to get the coilovers useful, ie not cheap (ive been here before, changed my coilovers 3 times untill i ripped out the entire front end and replaced it with toyota stuff).

 

now onto steering geometry,yes of course it will "change" the geomoetry, lowering the car changes the geometry..... i did a bit of an analysis on the S13 front end in ke70 steering geometry over at ae86dc, found there to be a few mm of toe in bump steer on full compression. i could never feel it in my car. but you must remmeber that the mcpherson strut has built in bump steer, the very nature of the setup has bump steer, you just need to design the setup so that the worst bump steer is out of the suspension range.

 

the main draw back of the s13 gear (as i see it) is that it is just so damn heavy, unsprung weight is through the roof, not what you want in a light car like a ke10 (or any corolla for that matter)

 

now onto the ke10 itself in question, i don't know specifics unfortunately, but i would be looking into fitting shock tube that is around the 50mm mark (ae86, some coronas) in order to be able to buy some decent shock absorbers (kyb, koni, bilstein...the list goes on). if you are going to be lowering the car you may require short stroke shocks and the easierst way to do this is to convert the struts to coilvoers (weld on sleeve kit etc)

 

if you are going to be running a 4agze thats alot of power and torques for the little tiny ke10 and i would instantly throw out the idea of ke30 brakes, they are worse than ke70 brakes....and they are pretty bad...., so your going to want a fair substantial brake and suspension setup to keep it all stopping and turning. also you will require this for engineering anyway.

 

if you decide to go with the ae86 front end then you can bolt on 234mm x 18mm vented rotors from the jap 86. now these arent that great, mine fade on the mountain roads. i would be looking into the rx7 caliper upgrade (mini disc?) fairly popular, and a nice upgrade. though that may be a bit big for the little ke10 (i think the mini discs are about 270mm?) on the other hand it may be cheaper to get the willwood brake kit for ae86 struts, super light and super awesome..and can be had for about 1000bucks.

 

though you will need to look at a mastercylinder upgrade, and a brake proportioning valve. (pending your front and rear brake choice)

 

for the rear end, ive never dealt with leafs but people have alot of success with them. with that 4agze you are prolly going to want to get a bigger diff, i would be looking at an R31 diff maybe, or just a T series and don't give it to much hell. both have a factory LSD available, and both have aftermarket 2-ways available. (though the factory R31 LSD is a bit ordinary)

thanks ke70dave pretty good read :)

 

I'm only looking for around 150 - 175hp outta it which is a lot in 720~kg

 

yeah I'm thinking i'll leave the ke10 diff in it until it breaks and then discover my options

 

as far as the ae86 front end swap, is that using the factory transverse leaf spring and that? or am i able to use a ke20 lca setup?

 

i had a google and didn't find much but a ke10 with ae86 struts with ke10 front but I'm looking to run a ke20 front end if i can

 

cheers jono

[ke70dave]

nah the 86 stuff is just normal coil over strut setup. mcpherson strut design

 

i forgot about the funky transverse leaf in the front.

a guy in that thread hints about putting 86 stuff in his ke10, sounds like a bit of work.

 

its also just occured to me that the ke10 would be steering box? dunno how that would go with all these changes, might have to convert to a rack and pinion...

 

it depends how much you want to spend and how much development you want to do. if you can get ke20 stuff in there easily, then you could find a bigger disc/caliper combo and get some adaptors made up to bolt them to etc. but that doesnt help much as i don't think there is much in the way of shocks for ke30's (besides standards)

this is a bit of a walk through on putting ke30 stuff into a ke10.

 

seems pretty easy, and ae86 is pretty much same setup as ke30 (mcpherson strut etc) as far as i know.....

 

on second thoughts it may not be as easy, as it seems they have adapted the ke30 stuff to the ke10 stub axel.

 

hmm seems you may be in for some customisation in order to get some chunky brakes into your ke10.

ahh well, spending a bit of time and effore making it stop is better then spending 10+ years fixing the car after it hit the tree/ killed someone.

 

thanks for the helo, a mates running a 4age smallport in his stock ke30 and that seems to stop fine. is the problem with the ke30 brakes being because the ke10 would be so much lighter?

[ke70dave]

well sure it may stop fine once..but can it do it a few times in a row?

 

especially with the ~150hp you are going to be getting up to speed pretty quick, you wanna be able to slow down quick too!

 

no point building a bullet car that can't stop more than once!

 

also it may be a legal thing as well, no engineer is going to give you a mod plate for a 150hp supercharged engine with 200x10mm solid rotors trying to hold it down (or whatever a ke30 has). and on that note, if you do intend on getting it mod plated, best to see an engineer before you start buying anything. just to know what your goal needs to be.

[Jono.C]

it's currently unrego'd. so i 'll have to get it engineered. which creates a problem. because for pit pass they require the car to have factory track etc..
