newbie on spoa

Post by elgordomuygrande »

Hello my fellow daihatsunuts.

As a newbie on this forum I'm still amazed about the tons of info you can find over. Still, I am wondering if anybody has done an SPOA conversion. I'm planning to do a body off restoration of my '83 f20 and, in the process, also makes some mods to the driveline.
So a couple of questions on this:

- what about driveline angles. Best thing is to fit a cv-driveshaft in the rear, I suppose. Are these available or do I have to fabricate one myself. Or is just slight increase in pinion angle sufficient?
- anybody an idea how I can mount the new springpad on the cast diff housing (I don't now if it's the same on Rockies, but one of my pads sits on the diff housing)
- Can I easily fit another engine, was thinking about a 22r toyota, it seems that they can easily be installed, with minor fabrication.

Hope any of you guys can help me on this....



:idea: :idea: BTW I don't know if lockers are still a problem in dai-land, but i think it is. A company in Germany seems to make electric and vacuum lockers for al the models, I'm planning to install them next summer because for me Germany is not that far.... www.offrotec.com

Well SPOA conversions i've seen on Daihatsu F20.
From what i noticed they used the plate that mounts the springs and turn them up side down and place it on top of the axle.
But the shock mouting should be modified to suit the change in the ride height. I noticed many people from where i am, Malaysia, do the short cut way and just bolt back the shock absorber at the existing position.
Coz if u do that after a SPOA the shock absorber will be "compressed".

U might have to check out the panhard rods, steering and propshaft.

Other than that u might have to extend little things such as brake lines and the axle breather hose.

Just my 2 cents coz i'm also very new in the off road scene and still learning.

Btw why do a SPOA?
Center of gravity will be higher.

Is illegal in Qld BUT a few have been engineered using diffs which were SPOA from the factory, ie hilux :) It's a grey area though :?

elgordomuygrande with spoa on those little old axles it will be VERY narrow and fairly high :shock:

Do you have plans to widen the track at all :?: For every inch you go up (4" or so with SOA) you want to go just as far out to maintain stability. I'd asumen more stability than standard would be good too. What tyres do ou want to run :?: The best way is to fit the tyres you want with as little lift as possible and as much width as possible. Stability is the key ;)

Sorry for the longish post but I reckon SOA on stock axles might make it a bit hairy to wheel :) If you must have big lift :roll: then consider transplanting in wider diffs to compensate ;)

Lockers won't be an issue with diffs from something more common either which is a big bonus hey ;)

Well Mick, as for the lockers I totally agree with you, I'm just a little hardheaded when it comes to my dai in combination with other make parts :) I thought about some rocky axles but it seems that they're only slightly wider than my F20's. And I need the diff offset.. maybe some toy axles?

I want to install 33" tires, think that is sufficient for the swb F20. I now run on 31's and I only lifted it less than an inch. The reason I opt for the spoa, despite the higher COG, is that I'm really impressed with the travel and ride of the standard springs so I won't mess with that. Will wheel spacers compensate for the narrow track?

Regulations on this are not that strict in Holland, so spoa an larger tires won't be a problem.

Kewl mate :) Just my 2c hey ;)

Spacers + heavily offset rims will compensate for narrow track for sure. You mould get 4 or 5 inches per side like that I guess :D :idea:
