GROUP BUY CLOSED

22mm Rear Sway Bar / Anti-roll Bar Group Buy




What does a sway bar (anti-roll bar) do? Basic explanation:
An anti-roll bar connects one side of the suspension to the other side, it is essentially a spring.
Imagine you are turning right, the left suspension compresses and the right suspension droops (causing the chassis to lean to the left, aka. body roll). With an anti-roll bar installed when the right suspension begins to droop the bar tries to pull the left suspension down at the same time, this reduces body roll. Or another way to look at it is that as one side of the suspension compresses the anti-roll bar causes the other side to compress as well.

The larger the diameter (stiffer) the anti-roll bar is the more "locked" each side of the suspension is to the other and the less body roll at that end of the car. On a front wheel drive car adding a stiffer rear bar will generally reduce understeer.

Here is how this 22mm bar compares to stock and Whiteline.
Bar torsional stiffness:
Stock 17mm: 91 (Lbs/In)
Whiteline 20mm: 175 (Lbs/In)
MustardCat 22mm: 268 (Lbs/In)​



$$$
Estimated group buy pricing, shipping not included:
  • 5 bars = $380 each
  • 6 bars = $367 each
  • 7 bars = $357 each
  • 8 bars = $355 each
  • 9 bars = $352 each
  • 10 bars = $349 each
You cover the Paypal fees.​


Shipping price estimates to give you an idea of cost to different areas.
Shipping is from Washington State via USPS:​
  • To California 90210: $55 shipped with tracking and $450 insurance.
  • To Texas 73301: $64 shipped with tracking and $450 insurance.
  • To Florida 32116: $74 shipped with tracking and $450 insurance.
  • To Quebec, Canada H3R1K2: $110 shipped with $450 insurance.
  • To Germany: $110 shipped with $450 insurance.
  • To UK: $120 shipped, no insurance available.
  • To Australia: $150 shipped with $450 insurance.
(FYI Australia requires a custom box no longer than 42", this will be a VERY tight fit and it is possible the finish on the anti-roll bar arms could be damaged during shipping.)
Local pick up in the North Seattle area is also possible.​




This sway bar/anti-roll bar kit will include:
  • 7/8" (22.2mm) 4130 Chromoly anti-roll bar with arms made of mild steel.
  • Energy Suspension 9.5158R/G greasable anti-roll bar bushings.
  • New chassis brackets to mount the bar to the car. Made of 1/8" and 3/16" mild steel.
  • 8 New JIS 10.9 spec bolts to mount the brackets to the chassis and the bar bushings to the brackets.
Additional options:​


Fitting info and disclaimer:
This bar does require trimming a small portion of the plastic fuel pipe splash guard as well as part of an exhaust bracket (if you are using the OE exhaust). I can't guarantee fit on any aftermarket exhaust because some places do crazy routing, however I can say it fits around my own 3" exhaust fine.

Some have asked about chassis tear though, like what can happen with Civics using thicker bars. All I can say about this is that I have not experienced or seen any sign of it happening on either of my Preludes that are running this anti-roll bar. I can't guarantee this for your car because every car is unique. If your car is rusted near the anti-roll bar mounts it might be possible for them to rip out, if this is the case I could make you some weld in reinforcement plates for this area.

Like all performance aftermarket parts this anti-roll bar is intended for off-road use only. The sole purpose of this anti-roll bar is to alter the way the car handles. You need to take proper care after installing it and not immediately try pushing the handling limits, the car will handle differently. If you use it on a street car and then drift off a mountain... well that is on you.



Payment schedule:
I'm thinking I want to break the total payment into 3 stages, which should be more manageable for people and allow continuous progress to be made (all prices are estimates):
  • Stage 1: This payment will cover all the raw materials, bolts, and bushings, and allow me to fabricate the bars and mounts. (Should be between $100-150 depending on total buyers and options.)
  • Stage 2: This payment covers the cost of post-fabrication heat treatment for the bars. It also covers the cost of powder coating the bars and mounts. (Between $60-110 depending on total buyers.)
  • Stage 3: Payment for consumables, labor, misc, and shipping. (~$150-250, depending on previous costs, total buyers, and cost to ship to your location.)


We will need at least 5 buyers. This list is for serious buyers only. Please reply if you are in.

Update: End of group buy final prices.

Since I estimated on the high side for things like materials and powder coat here is how the prices actually worked out at the end of the group buy:

Stage 1: $100
Stage 2: $60
Stage 3: $165

Total: $325, not including the optional bushings or shipping.

If you are looking to buy one of the 2 extra way bars I've made then that is the price, +$30 if you want to add the SuperPro bushings. PM with your shipping address and I can get you a quote.

You know I'm in for one. I already have the end links but I would like those other SuperPro Bushing Kit added as well.

I'm not sure I understand the question. Are you asking why there is a bushing there? It's required because of the style of endlink we use. The link needs to be able to tilt side to side in relation to the sway bar arm.

I wont be asking for Stage 2 until I am ready to have them heat treated. The list of members in the first post also lists who has paid so far.
