KW Rear Top Hat Question

[wparsons]

If you're only going about 1-1.25" lower, I probably wouldn't bother with top mounts that give more travel. If you're going to lower much beyond that, I would consider them.

Yeah I am doing minimal drop with coilovers. Do you know what is the stock measurement from the fender to the center of the wheel? Thank you!!

[wparsons]

Nope, not sure.

i know i'm resurrecting this thread, but i'm curious about the STI top hats / group N top hats.
So is 2011-14 the correct year range for STI top hats group n or stock that will fit KWs on a BRZ/FRS? I don't need camber adjustment, mainly just want to use other fixed hats so that when spring comes back around, I can simply take out the stock shocks and install the pre-set KWs without dealing with compressing the springs n such.

Thanks!

like i said, i have GR sti rear topmast so yes those will fit, i also have Group N fronts on my AST's but i don't know if they are STI specific or not or just a BRZ one.

Is there a disadvantage in having too much shock travel? Im installing kw v3 coilovers and is wondering how much more shock travel do i need. Planning to install stance lca too.

It's a trade off... using the upper mounts that give more travel costs you droop travel. If you're not lowered a lot you might be better off with a stock upper mount.

With our Tarmac 2s lowered less than an inch from stock, we're not even seeing 1.5" of droop travel on track. Like @wparsons said, we've got plenty of droop travel.

Here's a graph of wheel travel over a lap:

Yeah, I don't think you really need say a 2 inch lowering rear top mount unless you're absolutely slamming the car. Some droop travel is nice to have.

If we did a rear mount we might have a 0.5 inch lowering option in addition to a no-change. Just for other options out there. But those are not at the top of our list at the moment.

LOVE seeing this Jake !

So I've said it many times to people on the phone but never on these forums.

Travel is important. A lot of the cheap coilovers have very little droop and bump travel. Even the Ohlins , (IMO) are travel challenged and dont offer much lowering as a result. But our T2's and the KW V3's have a LOT of droop AND bump travel. The need for extreme lowering mounts is just NOT necessary ( if you have KW's or our version). And to be clear...this is for functional lowering. If you plan to slam your car then sure extreme lowering mounts are great and do give back what you take away by lowering 1.5 or more.

The notion of gaining some bump travel started for Subies back around 2003 when the GD Impreza was released and the inverted front shocks once lowered 1inch were essentially on the bump stops at static ride height. Our lowering plates then offered 3/8th lowering so it was getting things back in the right direction. The use of shorter bump stops ( by 20mm ) also helped.

Hope that helps to clarify for some.
