Best Springs on RX-8
 

I wanna lower my car (NOT SLAMMED) but i am having a hard time trying to decide what is the best spring for my stock shocks. I want a 1 to 1.5 inch drop. Please post pics with stock 18's on Titanium Gray with factory lip kit.

Tein S-Techs is a really good drop, 1.4in front and .7 rear, that's pretty close to what your looking for.
there's alot of people on the fourms who just have tein s-techs on if you search around.

I'm lowered on Swifts, and they rock.

Try search for the shock and spring thread.

Lots of good info.

Thanks for the feedback guys. Please can someone post s techs on TI gray with stock 18's.

Why should we have to do work for you? Are we getting paid? You can very easily find pictures yourself of S-Tech's on gray with stock 18s.

Search is the number one rule of this forum. It takes a few seconds for you to search, but to upload some pictures it might take members several minutes; not to mention you're the one that wants the picture, it might be a hassle for them to upload.

Yeah your right I know. I was actually asking which springs are the best. I am deciding between Tanabe or Tein. I am sorry I am very new to all this. I am sure I will be a pro soon. I am not a guy driver.:lol2:

Best is very relative and a moving target. Best in what way?

Which would be the best with stock shocks, but also giving it a really low look without any body roll.

without any body roll and you want to keep the stock shocks too?

Yes. There can be a little body roll but looking for it to feel better than what it feels like with stock springs. I am keeping the stock shocks on for now.

I have the Tein S-techs w/ stock shocks. It feels good and stiffer than the stock springs. Also, keep in mind that you'll have to eventually replace the stock shocks.

That's why some people go with the coilovers.

I would vote Swift springs, but you should really get new shocks as well to firm up the ride.

i've got the s techs on mine

springs won't make a huge difference in terms of eliminating body roll. you'll need shocks or sways to do it.

spend a little more money and get a set of quality adjustable coilovers. That way you determine the exact drop your ride gets. Do not be cheap and swap just the springs while retaining the OEM shocks.

I have the S Techs on eom shocks but I've notice that I need new shocks. I am with PDXHAK and all others to swap oem shocks. But if you cant afford them both then really no harm if you ride on oem for a while. gl

I agree that lowering springs, because of their minimal rate increase, won't do a whole lot for body roll unless the lowering is enough that the car engages the bumpstops earlier. It's not quite as bad as what some people think; modern MCU bumpstops don't engage very harshly and add rate quite linearly. However, it's still not the best for damper life and might make a car a little less predictable to drive.

However, dampers will do nothing in terms of eliminating body roll. Dampers don't offer a resistance to force and so they can't stop the body transfer that results in body roll.

i'm going to have to disagree. lowering springs will reduce body roll for 2 reasons. the first you have already said, which is due to the higher spring rate. the 2nd is that the car will have a lower center of mass, which lessens the effective moment on the car.

also, the dampers can affect body roll, in a sense. really what they can do is change how fast the roll happens. in a situation like a slalom, since you are going left right left right so fast, you can effectively have less body roll with higher damping force. this is because the car is not given enough time to reach its steady-state roll position.

Yes I neglected to mention CG induced weight transfer that contributes to body roll. However, the majority of weight transfer is not CG induced; it'll happen whether you Cadillac springs or steel rods for suspension, though obviously steel rods won't give much body roll at all. That is another aspect to consider, but I'm willing to bet that a lot of "reduced body roll" that people think come from lower CG is actually from engaging the bumpstops earlier.

Yes dampers change how fast the body does roll. I was talking about steady state though, for transient it's certainly different.

I might have to stick to springs for now. Just got the car a little bit ago and I'm gonna have to save some more money if I want coilovers. Think I might go with Tanabe gf's.

From what I've been told, if you track your car the stock shocks will get overwhelmed pretty quick with stiffer springs. Not sure if you go to the track or not.
