Speed bumps, dips.. and stuff...

Through my normal commute, I drive through a few speed bumps and dips. With a stock Zuk, I feel that there is almost no suspension on the vehicle when hitting one of those (even at low speeds). Since I drive through this every day, I want to smooth the ride out a bit as it would reduce the shock into the truck.

Am I correct to assume that it is the shocks I need to improve on and not necessarily the springs? I don't really need the articulation for rock crawling. Any recommendations? I would like to keep it as close to stock as possible without any welding.

Since the current tires are getting pretty worn, I am planning on increasing tire size from the stock to P205/70R15 to P215/75R15 (which is supposely the largest I can add to stock without rubbing). Would that help the ride?

I checked my speedo via a GPS yesterday. At 50MPH, the actual GPS speed is 46.8MPH. It isn't crucial as it will avoid me getting any speeding ticket (a ticket with a sammy, how it that possible? [img]images/graemlins/smirk.gif[/img]), but just curious on how you would go by fixing that?

Just a note: By lubing the steering joints, I was able to reduce/eliminate the groaning noises while steering at low speed. I am still waiting for parts from Rocky-Road to fix the transfer case shifter. Do they normally take a long time to process an online order?

Re: Speed bumps, dips.. and stuff...

i'd say it's the springs much more than the shocks. also, bigger tires at lower pressures will make for a much-improved ride.
as far as the speedo, there's no way to adjust it. just calibrate it in your head. ie., "when it says 55, i'm really doing 66mph." also remember that it's wrong by a percentage, not by a fixed number. it's not like a sammy can speed anyway - i just drive with the flow of traffic and haven't read my speedo in years...

heres some quick replies for you. Others opinions may differ.

The real answer is that a samurai is a small, short wheelbase vehicle and is always going to have a more choppy ride over stuff like that than a longer wheelbase vehicle.

to answer the question you asked: they're related. Better shocks will help a little with the stock springs, but longer springs will help more. You can move the rear springs to the front and replace the rears with springs from a CJ, or put on YJ springs, which are a lot longer. My sami has YJ springs and rancho 9000x shocks and rides really nicely on the road.

not appreciably, but it will make your truck slower to accelerate. The pressure in the tires makes moer of a difference in ride quality than that small of an increase in sidewall height. I would run about 20 psi with stock tires, personally. Less pressure and you start getting rolling resistance, more and you get less resistanec and better mileage, but the ride gets harder.

you don't. Just deal with it. If you change tire size it gets worse. Or keep your GPS all the time.

Re: Speed bumps, dips.. and stuff...

Since your speedometer reads faster than your actual speed, when you put larger tires on, you will likely be closer to actual.

Your 205/70R15 tires calculate to 26.3" and the 217/75R15 tire calculates to 27.7" and should have you at an actual speed of 49.3 mph when your speedometer reads 50 mph. That's pretty close.

Re: Speed bumps, dips.. and stuff...

Daxe pretty much has you covered.

I rode in a completely stock samurai this summer. The owner was maticulus. Replaced the springs with NEW stock originals... bushings, tires, etc. He went through it completely. This thing was a pleasure to be in. I mean it wasn't for me, but it handled well and drove nicely. If speedbumps are a concern your kinda in the wrong vehicle. Any vehicle with a truck-styled frame, leafs at the 4 corners, and a straight front axle isn't going to give you that caddy feel.

Re: Speed bumps, dips.. and stuff...

Nicely put Daxe, diplomatic even. (for one answer! LOL)

I will add you should check your speedo and your odometer. They can be off diferent amounts. I personally
am more concerned that the Odometer is correct or at least a well defied percentage off so I can correctly
log milage. You can check it using the roadside milemarkers, the white ones on the side of the road. They
usually have a mileage printed on them. At least they do here.

you can make a small correction using a different speedo gear in the Xfer. Suzuki makes 2 at 19 and 20 teeth
as I recall. It can correct 5% assuming its the right 5% direction you want to go. I have no idea why they
didnt do one up and one down.

Your other option is take it to a speedo shop and they can usually put in an inline correction gear box, I
believe at the clock end. Assuming the make one for the orphan suzuki speedo cable system, and that
there is room.

Re: Speed bumps, dips.. and stuff...

whoa...

if people the caliber of outlawms are thinking I am putting things well then I must learning some of this stuff. A little bit of experience doesn't hurt either, I guess.

As for the diplomacy, I have NEVER unleashed a word on this BBS that even comes close to the years of blistering diatribe I have spewed elsewhere on the internet. I have this tendency to be opinionated and say what I think that some folks seem to find abrasive. However, as some of the people who have met me in person might attest, I am actually a pretty decent guy. I think. [img]images/graemlins/shocked.gif[/img]

Re: Speed bumps, dips.. and stuff...

I miss the old days of being enthusiastic and ignorant. [img]images/graemlins/frown.gif[/img] knowledge is a painful thing.

OK..not really. [img]images/graemlins/cool.gif[/img]

for instance..the knowledge I have acquired has led me to reverse my own recent decision and decide to build the heck outta my sami instead of "streeting" it. This could be good... [img]images/graemlins/grin.gif[/img] I see the dreaded SPOA looming on the horizon. I just started feeling bad that I really got some good stuff on the sami and was gonna pull the carpet out from under it. It's GOTTA be a wheelin rig. there's no other way.

I now have some trux secured to build me a street rig outta tracker/kick things, instead. And that will probably last until I get all foamed up and start building THAT thing, too.

*sigh*... [img]images/graemlins/thud.gif[/img]

Re: Speed bumps, dips.. and stuff...

Well from someone that has never met you, and just knows you from your posts on this board, I think your a pretty decent guy already. (stop blushing) [img]images/graemlins/wink.gif[/img]

As for the Tracker/Kick thing... I think I see an axle conversion/longarm kit in your future. [img]images/graemlins/cool.gif[/img]
