Subaru BRZ different suspension / springs tuning

[Racecomp Engineering]

Subaru generally is VERY conservative with the balance of the car....lots of understeer tuned in through the springs and bars. Not a problem to change.

We'll get the spring rates as soon as we can.

Sorry Dave ROR and Old Greg, one too many Blue Moons. :happy0180:

Anywhoo... I'd be curious to finally read a head-to-head review between the FR-S and BRZ on the same road course under the same conditions. Subaru has tightly controlled BRZ test drives at their test track while Toyota has let reviewers hoon it up on their grand prix track, so you can't glean any real comparison of the handling characteristics.

i think in the past that has been because of the influence of prodrive and what subaru is doing off of asphalt. this thing is a road car so i am curious to see if it follows suit

I hate all the posts on here that claim to be quoting a source, but don't reference it ... however, I did read an Australian review that quoted a Subaru source that the front springs are softer and the rears are firmer on the 86 than the BRZ.

How's that for hearsay?

Good spotting Dave. That would be because I wrote it the wrong way around. Will fix it.

I'm expecting this car to have the same aftermarket support as the WRX/STI so you will have TONS to choose from.
I will probably throw the springs away the first day to fix the bad wheel gap.

There's that, but in the case of the GR (08-10) STI i think they just plain screwed up (or went too far with building in understeer) and then fixed things with the 2011 STI suspension. Just my opinion but looking at the spring rates not changing much between the GD and early GR chassis while the rear suspension layout completely changed they clearly realized that they didn't do it right the first time....
