bigo1966 Posted January 22, 2008 Share Posted January 22, 2008 Has anyone achieved great front flex on a Subaru??? I got the rear to flex excellent with air shocks/air springs, but the front is still an unsolved mystery. Orion Link to comment Share on other sites More sharing options...

Numbchux Posted January 22, 2008 Share Posted January 22, 2008 Flex/articulation. Why are the axles a hang up? too much travel = broken joints. but, the struts are the biggest limitation (assuming you don't have a sway bar...). need to find longer travel struts (good luck) Link to comment Share on other sites More sharing options...

Orion on the front of a EA82 you can go 2" beyond stock movement downward max , 1-1/2" easy , the auzzies seem to have figured it out Link to comment Share on other sites More sharing options...
bigo1966 Posted January 22, 2008 Author Share Posted January 22, 2008 Anyone replaced the front springs with ones with more coils? From some other car? Link to comment Share on other sites More sharing options...
Numbchux Posted January 22, 2008 Share Posted January 22, 2008 ^ no need.....the stock springs are pretty well matched, I think you'll find that your maxing out the travel of the struts. Those little a-arms aren't gonna travel too much no matter what struts you put on. very good point. the struts are the immediate limiting factor. but if you put longer travel struts, you'll be maxing other things out in a hurry (control arm, tie rod, axle, etc. etc. etc.) EDIT: I just realized you've got a buggy....so it might not be heavy enough to fully compress the stock springs. what springs are you running now? you may try some from an EA82 coupe or sedan....they're 12 lb/in's softer than the wagon or XT ones, and 20lbs softer than the RX ones.

bigo1966 Posted January 22, 2008 Author Share Posted January 22, 2008 I currently have the stock EA-82 Wagon springs in the front. With the rear so light the front doesnt flex much at all. The real reason i asked all these questions is if i was going to keep the buggy i was going to build a custom front suspension using hydrolic slave cylinders as the front struts. So the buggy in the end would have air shocks/springs on all 4 corners. Ive done a ton of research on this (http://www.pirate4x4.com/forum/showthread.php?t=261171&highlight=hydraulic&page=11) and Yes i know it sounds way out in left field, but i really think it would work. So basically you would order 2 of these slave cylinders (http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200309367_200309367) with the shaft very close to the diameter of the bottom of the strut. Yes i know the above cylinder has 2 clevis ends. you would have to order one similar to that of a snow plow lift or a bottle jack style. Where its a clevis mount on one end and a "solid" end on the other, around 1.5"od. Then just clamp that end in where the strut came out of and then you would have to build a custom top strut tower. I can explain it better in my head than in this post. And....now you all can tell my why it wouldnt work O Link to comment Share on other sites More sharing options...
bigo1966 Posted January 22, 2008 Author Share Posted January 22, 2008 http://www.peninsularcylinders.com/sp_weld.htm Red one on the right is a good example of on that might work given the right sizes. Link to comment Share on other sites More sharing options...
monstaru Posted January 23, 2008 Share Posted January 23, 2008 unless you had a reciprocating hydraulic pump, those would not work for the application you speak of.you see those are designed to be pumped full of fluid to actuate.then relieved of the fluid to compress.good idea, wrong application. and there are already automotive applications available for this. ie: flippin you switches yo.pro hopper has one of the best gigs around. http://www.peninsularcylinders.com/sp_weld.htm Red one on the right is a good example of on that might work given the right sizes.

bigo1966 Posted January 23, 2008 Author Share Posted January 23, 2008 You add some oil to the cylinders and then fill them up with air. Oil to lube, air to lift. Link to comment Share on other sites More sharing options...
monstaru Posted January 23, 2008 Share Posted January 23, 2008 ok go ahead, i'd like to see it properly performed. just a question though, have you ever messed with anything hydraulic?whether it be cylinders,switches,or pumps?just curious.cheers, brian You some oil in the cylinders and then fill them up with air. Oil to lube, air to lift. Link to comment Share on other sites More sharing options...
bigo1966 Posted January 23, 2008 Author Share Posted January 23, 2008 Actually yes...there arent too many things i havent messed with..... On the buggyroo2 i think ill give it a shot. Link to comment Share on other sites More sharing options...
Numbchux Posted January 23, 2008 Share Posted January 23, 2008 You add some oil to the cylinders and then fill them up with air. Oil to lube, air to lift. using a hydraulic cylinder with pneumatics doesn't really work all that well.... and like I said, it won't be long before you max out every other component of the front suspension. the rear isn't too complex, so you can get away with alot more..... I say throw some sedan springs on it and see how it goes. you might notice much better travel that way. Link to comment Share on other sites More sharing options...
Mike W Posted January 23, 2008 Share Posted January 23, 2008 Someone modified stock struts to take replacable strut inserts so if you find the right size hydraulic you should be able to do that too. But it still seems like to get more travel you need a different IFS setup. There's truck stuff but that's heavy. What about Audi stuff with 930 CV's?

TeamCF Posted January 23, 2008 Share Posted January 23, 2008 And....now you all can tell my why it wouldnt work O hehe. Anything can work as long as you are willing to put in the time/money. I say if you have the desire go for it. I'm sure 4" lifts on compact japanese family cars was thought to be a total and impossible waste at one point. Now ya see them all over and they do well. Of course like was said hydro cylinders with air may not work the best but if you can get it to work then thumbs up to you. Link to comment Share on other sites More sharing options...
bigo1966 Posted January 23, 2008 Author Share Posted January 23, 2008 Well now everyone has me scared that i would destroy the front suspension of the car. I figured I could do it for around 300.00. Link to comment Share on other sites More sharing options...
Uberoo Posted January 26, 2008 Share Posted January 26, 2008 I always thought the radius rods limited a fare bit.I know when ever I jack the front up on mine it seems like the radius rods are binding at the lower ends of travel Link to comment Share on other sites More sharing options...
monstaru Posted January 26, 2008 Share Posted January 26, 2008 do you have any pics of your car yet?

Numbchux Posted January 26, 2008 Share Posted January 26, 2008 I always thought the radius rods limited a fare bit.I know when ever I jack the front up on mine it seems like the radius rods are binding at the lower ends of travel they definitely do bind, but the strut will reach maximum extension before they actually limit anything.... but good point, they'd restrict things too if a longer strut were used.

bluebaru Posted January 28, 2008 Share Posted January 28, 2008 You add some oil to the cylinders and then fill them up with air. Oil to lube, air to lift. air is definentaly not good for hydraulics because it can compress much easier than an actual hydrualic fluid the hydralics(i guess technically it would be pnuematics) wouldnt do anything the air pressure would just rise in the chamber. thats why they can use air in shocks because it can be compressed and then the pressure provides rebound. the oil that you would find in say an air/oil shock is to provide damping. which slows down the return action of the shock so it keeps your car from feeling like a pogo stick.
