Are there any real benefits to lowering an inch using springs?

Lower center of gravity ...which reminds myself of something I've always been pondering.

It's been marketed and known that the 86 has an "ultra low CG" only bested by the Modena 360, LFA and GT3, by only slightly and less than an inch (around .73 iirc)....so, does this mean that after an 86/brz/frs is lowered, even a mere 1", that it has the lowest center of gravity of any production car in existence, including super cars??

If yes, sweet! Too bad it's only 200hp tho, hehe

I recommend the SPL part.

Do you think a Rear Toe Arms is needed as well?

Only if you can't get the toe you're looking for. In most cases, it's not.

If I were to purchase springs that don't come with bump stops, how would I determine which bump stops to get?

Lengths I can't tell you off the top of my head...maybe 7 inch front and rear?

Diameter is 60mm.

KW makes their own springs. We use their "race" line for our T2s. Slightly lighter and more consistent. That used to be an option for their own stuff, not sure if that's true anymore.

I have researched the JRZ, Ohlins, T2,s and MCS. MCS has a kit that makes them CS legal. I have had T2 on my STI, but found a little hard for DD, but great for auto cross. Then I have the post by RCE on the JRZ & Ohlins.
The only one without a lot of feedback are MCS. Great dampener doesn't cut it.
Thank you for the info. RCE loved the JRZ, but you get a better warranty and dust boots with the Ohlins.
Front runner is the Ohlins and a move to STX. Was hoping to stay CS, but it will more fun.

Ohlins, T2s, JRZ, and MCS are all excellent.

T2s on this chassis are a little more forgiving than they were for STI for what it's worth.

Ohlins are just amazing shocks. I think Myles in the office finally felt like our car was about perfect when we put a custom sprung version on our car. Yes it's only a 1 way but it is so damn good. Put them on, dial them in, and enjoy on the road and track as the name suggests.

MCS I don't have as much experience with, but their background is solid and the initial feedback is positive.

JRZ can be fantastic. Definitely a step more toward the track than others, but with excellent valving your concerns won't be about ride. No dustboots or bumpstops on east coast salty roads may make you feel a bit more careful driving them. Skip the JRZ RS and go with either JRZ RS1 which are a 1 way and cheaper OR the JRZ RS Pro which are more expensive but a 2 way. JRZ RS is a 2 way but we found the RS1 1 way to be preferable in our testing.

For competitive auto-x or a more track focused set-up I'd lean towards JRZ and T2 due to more customization and ability to dial them in just right. Ohlins will be the best all around do everything with minimal compromise set-up.

I disagree, or will at least say it depends.

JRZ RS certainly are not on par with TTX and maybe not with Ohlins R&T.

Ohlins R&T is similar to JRZ RS1.

JRZ RS Pro has a big advantage over Ohlins R&T with the 2 way adjustability, but then it's a little more track focused (and expensive).

Internally Ohlins are awesome, just out of the box they're a little more of a compromise than JRZ.

Would the compairison be those JRZ's everyone is talking about? I'm assuming, from past posts, that they are more worth the money than the Ohlins.

I'm a fan of Ohlins and JRZ, but depending on your budget and goals there may be options at different price points.

What kind and what size tires do you run?

It depends on the springs.

You can get some benefits with some of the higher quality springs out there. Going beyond an inch with lowering springs is IMO giving up too much in ride and handling to look good.

I would purchase springs that come with bumpstops, but that's just me.

and also dynos of Monoflexes, SRCs, Ohlins R&Ts?

And dynos of the cheaper setups: B8 (once someone has them) vs T0s vs B14s?

Oh yeah, this!

I swore we posted our shock dynos a long time ago in our own thread here, but it turns out we never did.

This is T2s on soft, 9 clicks comp and rebound, and hard with T0 in there as well.

I am running stock wheels and 225/45/17 rivals.
Budget is open al the up to the Ohlins. Checked on JRZ's the other day, and ya I'll put them off until I win the lottery. Lol
I consider the MCS just for the fact that I would be able to stay in street classes.
But for the price point and what you get, Ohlins are point or two ahead.
I'm just going to HAVE to find people with various set ups, try them( passenger seat) and pay for lunch.
Trying, sorta, to avoid being bitten by the bug. Sorta. Lol

Wow that is a large range of adjustability. How many total clicks of adjustment are there? And would you happen to have dynos for the V3's?
