Suspension Tips, for those who want to lower this car.

Cool...where can I get a set? If not, are swift springs pretty good?

Swift also has different springs for frs and brz respectively.

Are the swift springs a good alternative to the rs*r springs?

Thanks for your advice! I'd hate to mess up my cars handling at the expense of aesthetics - but let's be real, I'm going to lower it. I just want to do it right and economically.

Thanks!

They work with stock shock absorbers, and have different rate sets of progressive spring matched with different part# and rates for the FRS and BRZ to match to even the slightest difference in the two cars OEM shocks.

PM'd you the link

Now when you say the SuperDown Sus springs will work with the stock struts - what does that mean?

I'm guessing because of the more aggressive spring rates, they will wear the struts faster - but by how much? Will they last 1 year, instead of 3?

Thanks for your help on this. I found a place to buy the springs (info@rs-r.com) but now I'm worried about the longevity of my stock struts. If I need to replace my struts so soon after, I may as well wait, and then look for coilovers.

Had my RS*R SuperDowns installed today. Initial impressions are here:

Thanks for posting your thoughts. I wonder how MOTO can chime in on this - supposedly lowering the vehicle with stock wheels/tires will worsen response. Possibly you haven't explored the true limit of the vehicle - and this makes sense, since you were testing on the street.

Would you mind give me some advises on my setting. I just order goodyear eagle 225/40r18 front and 245/40r18 rear with a set of 18X8.5 and 18X9.5 rims. Will this be a proper setting for street driving and some corner-fun?

I am also thinking to drop it a little bit. will these TANABE GF210 spring perform good with my new wheels? If not, any lowing spring that you recommend?

0.6" Front Drop
0.9" Rear Drop
Front Spring Rate - 2.7 kg/mm
Rear Spring Rate - 4.5 kg/mm

I just do not want to go coilovers because they are too hard for street driving.

Thank you so much !!

I can elaborate on definition of soft as "compliant, well damped, and allowing enough stroke at low loads" OF course that can be had in different combinations of factors but generally, the suspension on this car needs to MOVE.

Stock Tires + Stock Tires = pretty darn good.

Low+ Stiff+ Stock tire = bad, hard to rotate, easy to understeer (plow)

Soft + mid-height -20~30mm (or plenty of stroke built into coilver) + medium grip street tire = FUN, Fairly quick, easy to handle, and close to original setup.

Low+Stiff+Race tires = proper race car setup, but requires a lot of driving skills to make it go fast.

And the main reason that I go 225 front and 245 rear is for look. I knew I will lose some oversteer and some fun.

If I already purchase these tires and rims, is there any spring or coilover setting can help me to build a car that similar to the stock setting? I do not want it to be really grip cuz I need some corner-fun on the street.

Thank you again.

BTW I have FR-S with five axis body kit. Do not want to drop too much, and still want some oversteer like FR-S OEM springs. Thank you MOTO

Where to buy the RS*R springs?

PM'd you think link (since they're not a board vendor).

[SurfAndSand]

So the RS*R springs work all right with the stock tires? What's the verdict?

I would assume the increase in spring rates would overwhelm the levels of grip available to the stock tires.

The stock tires work very well with the RS*R springs. The increased rates well within the range of many manufacturers and under even TRD. Source = this list http://www.ft86club.com/forums/showthread.php?t=8739

i have hanook ventus v-12s with my super downs, and they seem to be an awesome combination so far.
