Subaru BRZ different suspension / springs tuning

[spin9k]

[QUOTE=MatadorRacing_F1;89266]This. Both Seem to have Michelin Primacy as standard tyres. Perhaps the Bridgestone RE86 may be offered as an "option"[QUOTE]

Best option 'Tire Rack' - "Have it your way"

From the recent reviews it sounds like it may be as simple as the Subaru having a slightly smaller rear sway bar.

suspension will be changed on this car for me no doubt. factory doesnt even matter to me. but motons/ohlins are in the supercar category for suspension modifications. theyre just a tad bit more dollars than your other typical aftermarket brands.

however the aftermarket suspension for the BRZ/GT86/FR-S will be huge. i mean HUGE. you will have plenty of aftermarket to choose from. and if they are indeed parts bin impreza struts/springs/housing, it will be even larger library of parts to choose from because theyre all so exchangeable between the cars.

as buyers, this can only mean good things for us.

Just because they fit doesn't mean you should use impreza coil overs.

obviously not but just the fact that it saves the aftermarket tuners money from building their parts to fit our cars, they could just revalve them and package them with different springs. in the end it just means higher production rate, thus lower costs for consumers.

how big do you think the market can get for such a limited production car? when you say huge it makes me think miata or civic. my guess would be on the smaller side of things...besides, how big do you need it to be? you really only need quality stuff. big in my opinion just means megan gets involved. as long as this raises enough eyebrows for a tein monoflex or something better it should be fine

Someone above mentioned smaller rear sway bar in the BRZ? Where did that fact come from?

It's not a fact, Dave-ROR said it could be as simple as a smaller rear sway. It could be spring rate, it could be damper valving, it could be a slight change in end link position. We won't know the facts until Subaru and Toyota release them... everything else is speculation at this point.

eh? Old Greg said that I said depending on the price of the scion rear springs I'd consider swapping them in (until real suspension setups are made for the car).

Most likely (unless it's sway bar) the differences won't be published.. at least I don't think I've ever seen an OEM publish spring rates before.

Not a fact, just the most likely culprit in my opinion. Simply put, the way the mags describe the Subaru as apparently having more understeer at the limits of adhesion implies that the Subaru has proportionally less rear roll stiffness than the Toyota. Now, it's possible that Subaru changed the spring rates, either slightly stiffer front or softer rear, but it doesn't make much sense to me. Subaru already has a large variety of swaybars for the impreza rear suspension designed and in inventory. It makes better financial sense to make the change with the swaybars. I really doubt it's a difference in damper rates though, as that would effect transient balance, not steady state balance like the reviews seem to be talking about.

im expecting megan to get in. basically everyone who has gotten on board for making coilovers/springs/camber plates/sway/strut bars for scion and subaru in the past 8-10 years.

Subaru worried that ex pushy Impreza owners will scare themselves?

Hey! I resemble that remark.

The Impreza will oversteer plenty if you do it right, even my open-front-diff'ed wrx.

It's nice that it will likely just be a bar or spring change, unlike the geometry change of the mid-model SW20 MR2.
