MrH's BRZ Thread

So you aren't going to run a camber plate to adjust for the negative camber from lowering the ride height?

Not a big deal for track use but it won't help tire life on the street.

Considering it.  I have to figure out where the stock top mount puts me in terms of camber.

Are you running the stock tire size?

[MrH]

Are you running the stock tire size?

Lol, no.  Same rolling diameter, but I'm running 245 width all around now compared to the 215 stock.

[FlatBlackCaddy]

Same rim size though?

[MrH]

Same rim size though?

No.  Same diameter, wider rim though.  Stock was either 7" or 7.5".  I'm running 17x9's now for my summer setup.

Nice!!

[giant_mtb]

Pretty!

[FoMoJo]

You install them yourself?

[MrH]

Haven't put them on yet.  I was going to do it myself in the garage, but I've got a friend that offered to help.  One of his good friends has a garage with a lift we can use

I've been pricing out a turbo kit.  I think I'll pull the trigger this fall.

2700 lbs, 330 hp at the crank

Will the stock bottom end take it?

[MrH]

Will the stock bottom end take it?

Yep, no problem.  It's a crazy high compression ratio from the factory (12.5:1), but everything is pretty bulletproof.  I don't trust running too much boost, but 7 psi at that kind of compression is all it takes for 300+ hp.  Tiny little turbo that spools almost instantly.  It'll be kind of a strange setup though (oil scavenging pump running off one of the cam shafts).

[FlatBlackCaddy]

So those coilovers don't have separate height and preload adjustability?

[MrH]

So those coilovers don't have separate height and preload adjustability?

Nope.  Just the lower spring seat is adjustable, which adjusts the preload and height.  The body of the shock is threaded, it's not a sleeve.

I think im going to pick up a set of PSS9s soon.  The adjuster is by all accounts rubbish, but for my car I like the spring rates and the quality is top notch.

[MrH]

Why do you say the adjuster is rubbish?

I didn't like what I saw with the pss9s for my car, so I'd rather have some adjustability.

[r0tor]

From all the shock dynos I have seen, the adjusters have minimal impact towards the lower velocities that primarily effect handling and large impact on higher velocities that effect ride comfort.  Also its noted that the PSS9 really only have a full hard, full soft, and medium range as 7 of the 9 adjustments in the middle dont do much.

But saying that, for RX8s IMO they have a perfect streetable spring rate, great quality, great diggressive damping curve, and a good price.

[MrH]

Finally got time on a lift tomorrow night. Full day of work, then karting, hopefully get these things on in under 3 hours. I'll get an alignment some time in the next week or so.

Is it a drive on lift?

Takes me about 40 minutes to do an alignment on mine, might as well squeeze it in if you have time.

I've been putting off getting some slip plates and corner scales for awhile, probably should stop being a cheap ass and just get them. The slip plates would make the alignments much faster.

Yeah, that's just the nature of the beast unfortunately.  You can only get so much variation in low speed damping by changing the pre-load on the discs.  The adjustments are pretty linear though.  Not a huge range, but it steps pretty progressively.

More importantly though, I liked the valving of the PSS10's better.  I doubt I'll change it much once I find a setting I like.  I'll report back once I get them on tonight

I'm not sure what type of lift they have.  There's a specialty subaru shop down here that has a ton of BRZ experience.  I'm going to let them corner weight and do the alignment.

[MrH]

Coilovers are on!  Took awhile last night.  About 3 hours start to finish including setting the ride height.  Top mounts didn't slid over the piston rods like they were supposed to.  They're about a 1mm off, had to drill out the top mounts slightly.

I'm exhausted.  I need an alignment and either the front needs to be lower or the rear raised slightly.  The car is angled up more than what I was at previously.  Looks infinitely better.  Rides great on small imperfections.  Big modulations in the road upset it quite a bit last night.  Turned the damping up on the rear a bit and it feels a lot more controlled now.  I'll play with the damping more once it's aligned and corner weighted.

Pics of lowered briz!

Here's a few I snagged in the parking lot at work with my phone.  I'll get much better pictures once I get the ride height figured out and it's above freezing.




And from the install...

[Secret Chimp]

That is loads better.

[MrH]

Front needs to come down about 5-7mm more still.  The rear is about perfect.

[r0tor]

Whats the actual difference between the pss9 and pss10 anyway?

[FlatBlackCaddy]

What do you have for tires on there.

Also, I see you park out back with all the VW tools. I'm sorry.

[J86]

Is it a rule where everyone must back into their spaces?

Nice looking car.  I always love Subies in that blue.
