This link kit will allow for wider tires and an extended range of adjustment for camber, caster, and toe. Note that this kit will pull or push the lower knuckle in and out. Additional upper knuckle camber adjustments such as slotted coilovers or camber bolts are required to dial out positive camber if lateral links are set to min length.

The kit will start at $500 for the first 5 orders and then $20 off for every order over 5 up to 8 orders. That means that if we get 8 people in on the group buy the kit will cost $400. Buyer to pay shipping. Rods will be ready two to three weeks after 5+ slots fill up. Deposit of $100 upfront.

Details

• Group buy will remain open till Jan 15th 2011
• The kit comes with two adjustable trailing arms, bushings, and 4 lateral links.
• All joints are rated to 27,000 lbs,
• Rods are made out of 4130 chrome alloy rated to 30,0000 lbs.
• Lateral Links are ½ inch shorter then stock
• Min Length 19 inches
• Max Length 21 inches
• All orders come with FAF and AAC stickers

Options

• Links can be coated or uncoated. (+$50 for coating)
• Rod Colors: white, silver, gold, satin black, yellow, blue, green, pink
• Bushing Colors: blue, red, black

Pics

• Rods will have built end wrench ends to minimize welds)

I know what Im buying at the end of the year

Should fit BAs also, since the rear multi-link suspension is near identical between BJs and BAs. Hmmm, what are you doing next weekend Marc?

[Rupewrecht]

Aren't they the same as these?

Same type of suspension gear but different seller/brand.

I think there might some reference to the Megan gear in the GI thread.

[Rupewrecht]

Ah yeah, so i see. My bad, should have read the link!

Eh, so you need to slot the shock mounts and/or get adjustable camber plats for the top as well, otherwise you end up with positive camber? Hmm...starts to become expensive then!

Measurements, center hole to center hole:

- Minimum Arm Length: 22 5/8"
- Maximum Arm Length: 23 13/16"
- Max. Length assuming 5/8" minimum thread engagement.
- Inner diameter of center hole: 7/16" and 1/2"
- Bushing width on both ends: 2 1/2"
- Adjustable threaded rod diameter: 5/8"

Stock Arm Length: 22 1/2 (center hole to center hole per my measurements)

Based on all that the Megan part seems somewhat limiting. The part helps with camber but not with pulling the spindles in. My goal is to work with the fabricator to create a reliable lateral link that gives the tuner a wide range of adjustment including narrowing the distance between the spindles for a more aggressive wheel set up. Based on the provided Megan specs their lateral link's really cant do that.

Thanks for the lead nun the less.

From this out of the GI thread, the aac bars are shorter overall, which equates to more rim space uunder the guards

10" is crazy wide on these cars
I've got 7s and it's enough to make it almost impossible to slide and enough to launch faster than a commodore

[project.r.racing]

I might invest in some Megan lateral links for my car. The right side toe adjustment is broken. So these will solve that issue. And I can control/increase camber also by extending their length.

You'd want some super light rims of you went 10" wide on a sp20 lol. My cousins SP 20 needs this haha he has rims off a s15 on there haha

Sounds to me like we're coming up to measure?

Just wanted to show what it actually looks like bolted up:

as you can see there is plenty of room now for larger wheels

And basically how your able to wider rims/tyres:



essentially by shortening the lateral link arms you can pull the spindles in further from the fender allowing for more clearance between the outer edge of the strut and the fender.

[project.r.racing]

you mean spindles/uprights further from the fender right?

how do they go with camber angles with the lower links pulled inwards so far?

Camber bolts I would say. Lol

[Cosmo Dude]

Sorry but basic geometry says that the strut will be closer to the tyre with this solution even if you slot the lowest hole in the lower damper mount. Of course I'm talking about the McPherson strut on the BG, BA and BJ not double wishbone of the BK or BL.

Fixed

I would think the best solution for added camber would be to adjust the bottom links to give you more negative camber? The kit is pretty much designed for little to no camber, but to run bigger rims/tyre combo's.

Obviously you'd run these along with coilovers (smaller spring etc) so that you could run wider rims/tyres

Take a look at your existing springs and dampers. The springs sit above the tyres, where do people find 'skinny dampers'?

[rodhog]

What an absoloute waste on anything but a dedicated track car. Talk about RICE or Show performance. 8.5inch on car under 1300KG and well lucky to be 300HP. Plus rose joint ends it's like someone wants bounce around the streets thinking it's goign ot make it a better car. Rocks in ones head. wheels are not even driven, minimal carrying weight.

Adjustable arms yes can be handy - rose joints if your willing enough (why not buy a real race car )
but shorten them and lengthn this to Fit wheels so wide. ?

so I can see 9inch on the back but what about the front.
Going to space them shorten rack steering angle (most common) beat the gaurds inner and outer ?

Well I guess it's another each to there own.

[marcs_sp20]

run a rim with less offset - simple!

I plan on buying this kit & BC coilovers at the end of year, the plan is to run a 18x9" rim on the rear, seems do-able at the moment, so offset would have to be around +15

In short Marc there calling you loco, crazy, nuts, bannanas, and etc. lol

Impetuous maybe, this is a big change in suspension geometry. It changes the way the springs and dampers work, the roll centre etc... all for what is essentially cosmetic reasons.
