Okay guys here is the lowdown on what I've been thinking about doing. I was planning to buy the Racing Beat spring with either the kyb/tokico struts. Here is the problem I am running into. I want a little drop but I am more interested better handling.

http://forum.mazda6club.com/index.php?show...44879&st=15
3.5 Eater ordered the sedan springs in the front and h/b springs for the rear. His drop was 1.25"/.65". So from what I read the front is .25 lower than rear.
Does anybody know or has done this with sedan springs 6s in the front and h/b in the rear on a 6i?

6Venom put the Mazdaspeed springs h/b on his car. To me the rear looks a little lower than the front.
Has anybody put the Mazdaspeed h/b spring on a 6i sedan. I've looked but didn't see anything. What drop do you think it would give me. I suppose the ride will be stiffer since there designed for a heavier car?

Finally
What do you think the spring rate increase will be with the Racing Beat springs that are different in the front/rear? My concern is what will the cars handling characteristics be? I know they are designed for a heavier car but I'm just confused.

Hell I might just order the Koni's and run stock springs. :headscrat:

Thanks for reading and any input would be appreciated.

If your interest is handling The RB i sedan springs look good for an i sedan, .75"/.5" F/R. Nice, linear springs. The MS i sedan springs look too low up front, and at least the rears are progressive.

"3.5 Eater ordered the sedan springs in the front and h/b springs for the rear. His drop was 1.25"/.65". So from what I read the front is .25 lower than rear" (6s atx sedan).

For racing, you want an even drop. Front gap is supposed to be bigger than rear. Evening the gaps is cosmetic, and results in more than oem car tilt. The oem front is lower than the rear to start with. 3.5's car dropped more in the front, so that his front gap is less than rear by about .38". This is similar to the MS hatch springs on a 6s sedan.

Venom's 6i hatch mtx looks good, with MS 6s hatch springs. If you look at body lines, not gaps, the front is still lower. If you put these on a i sedan, the look would be higher in the front and rear ... not sure if any drop would result.

The RB i and s rear sedan springs could be the same, as is the case with MS, and oem springs. Going RB wagons in the rear would be little if any drop. Rates likely ok, mostly a longer free length.

Consider also the tanabe 210GF ... rear rate bias, and 1.2" drop.

several rear bars available for tweaking.

RB (F/R 20% increase over OEM) with Konis. These will give you better control and road feel, while still maintaining plenty of comfort. Not sure about the Mazdaspeeds, I never have liked the fact that all the v6 sedan owners are buying the hatchback springs, this only affects the rear springs since the fronts are the same with those kits.

Biggest thing is to stay off the bumpstops. The racing beats specify how much bumpstop to cut, Mazdaspeeds do not....probably because of CYA. If you ride on them, handling dynamics will be unpredicable when the road is bumpy. Steering won't be as crisp either.

In the first link you provided it gave exactly what you needed to know if you were going to consider the Mazdaspeed springs:

What is your 6 model?

If your ride is a V6 Sedan or Hatchback, the Mazdaspeed Hatch springs will be best for you. Look at the pic I posted.

If you have an I4 sedan, then the regular Mazdaspeed springs IMO. Bfrere has them on his blue sedan.

Besides that, the Racing Beats are nice so I hear....


So if you only want 1/2" of drop go for the RBs or if you want a little more then that go for the MS springs...

Side note: I am ordering my MS Sedan Springs for the I4 in a couple of days from the group buy

Fine springs, but with handling a top issue, I'd pass on these for 2 reasons:

1) too low in front for full suspension travel:

2) linear springs are better. at least the rears are dual rate springs. Box of MS 6s sedan springs, but both 6i and 6s have same dual rate rears (tight then loose coils)
