I ran a Progress RSB on my old GSR and it's compatible with ITRs as well. https://www.progressauto.com/products/s ... ductID/824

I just asked Type R Expo sponsor Acura Express Parts / OEM Parts to confirm, I couldn't find it online.

King Motorsports is a Type R Expo sponsor that sells the Mugen RTA for $140:

I would advocate to support those that support your community. :thumbup:

The ASR 24mm grey bar

There is also the Mugen 26mm rear sway bar that Christian has mentioned a few times, but I don't know much about it.

Edit for the CTR, I believe Karcepts has this bar

I remembered Mugen while on lunch, thank you. I have one sitting in the closet. :hammer:

At this point, I will split the aftermarket section into Static & Adjustable. I appreciate the quick feedback!

Eibach also makes a kit. I have a write up teed up once I source a replacement photo host.

Yeppers, the 26mm solid was, IIRC, about as stiff as the 0.95 wall ASR bar on soft? I think they’ve got 4 wall thicknesses maybe? 0.95, 0.125, 0.25, and solid? Or maybe I’m crossing that up with some of the bars you can swap in from Speedway. :lol:

It may be worth mentioning on the swaybar page whether the rates referenced are single wheel bump vs double wheel roll.

Sadly, the MFG's don't state that information. Fortunately, we should be able to get clarification from Eibach.

I posted over in the other thread... looks like it’s single wheel.

Stupid question, but a shortened shock body would force the car to sit lower? I've been weight options on changing things up a bit on my car, and was wondering about koni race shocks that are shortened or the whitner racing bilsteins (I recall from a slip angle podcast they are shortened also).

The shortened shocks force you to sit slightly sit a low lower than stock ride height by limiting the range of adjustability in height? I know I am compromising my car, but I really do not like to be that much lower than stock ITR ride height (maybe half an inch to an inch is my limit), but at the end of the day my car is still a street car and it needs to be able to get up through speed bumps and driven on the occasional bad road in addition for the weekend autocrosses I do.

Another question, has anyone tried Redshift Motorsports BC coilovers with Bilstein Internals?

https://store.redshiftmotorsports.com/p ... series.htm

The price seems fairly reasonable, but I am wondering about how good is redshift in regards to providing their services. My only third hand experience was a friend was really happy with her modified to use Konis on her STS GD3 fit that didn't have a koni yellow option.

The “shortened body” potion of things is relative to the body height above the spring perch. As a result, you can still your threaded perch up and get roughly the same as stock ride height. With the shorter body, you get a shorter piston so I guess it would be theoretically possible to top out the shock on a big droop? Realistically though, I bet you can get the ride height you’re looking for on any of the shorter body stuff.

Edit:
Shenefield at Redshift certainly knows Honda stuff... is talk with him first as his valving is going to be structured around the way he sets up his cars. A buddy is running his stuff on an FG (IIRC) Civic and likes it... but he’s running a really softly sprung front end vs what I’d do.
