On Friday, a friend and I installed all of the suspension goodies that I've been accumulating over the last few months: Global West rear lower control arms, Hotchkiss front and rear sway bars, ZQ8 bumpstops, and HAL QA1 12-way adjustable shocks on all 4 corners. Man, does the SSled ever feel different!

The factory DeCarbon shocks were well worn with 94K miles on them. At least one of them (driver's side rear) was completely toasted - no damping left at all. I've only driven it for 2 days and am still fooling with shock settings (4 front, 5 rear feels best so far) and getting used to the changes. But, these parts have transformed the SSLed to be much more agile and responsive. I can't wait for the next autocross!

I'm happy about your results, Lead! The Bilstiens
made a huge difference on my car. I've still
gotta do the front control arm\spindle upgrade,
new upper arms, Hotchkis springs and RCA's on
mine also. All sitting on my shop floor awaiting
install.. Then give myself a freakin' ulcer picking
the right sway- bars.

Terry,
You feel like this ---> huh..! My old cop car got near the same treatment too. Considering the Hals backed all the way out [left turn on knob] as #1 setting [not zero]; then, my fronts are set @ 3 and rears @ 4 on Hotchkis lowering springs, HO front & rear sway bars & 18" tires/wheels.

I don't have any other rear goodies installed yet but can hardly wait to do so...

Enjoy the ride---George

Hulka - I feel your pain. The sway bar package decision was the most difficult one to make. I know that the F-body front and HA/HO rear bar combo is the popular option before it is more agressive, but I decided to go with the more conservative Hotchkiss setup. I thought that it would be a little more accomodating on the street.

XBOX - Yes, it is quite a change. It almost is like a 4-door Vette now. [img]smile.gif[/img] I hope that you upgraded to an aftermarket LCA when you installed your rear Hotchkiss bar. If not, the 400+% stiffer HO bar will rip the stock LCAs apart.

Yeah, Lead, I'm about 85% sure I am going with
Hotchkis also. I've read horror stories about
the HA bars, that pretty much made up my mind.

Terry,
I hear ya about those rear lower control arms & the skimpy stock bolts now holding this rear HO bar; it's like an accident waiting to happen!

My car is down though: Rebuilding the alternator right now & waiting for the Racetronix fuel pump & harness kit to arrive [dead fuel pump].

I do have brand new Global West rear lower control arms in the garage [special order 3/4" extended version]. I phoned "Steve" @ GW today, he says: "We have adjustable extended rear upper control arms on the drawing board." I pre-ordered a set & so has Bill Harper. We need more guys to phone Global West to order these puppies so they will produce them in time for June ISSCA Annual Show.

I told Steve about the math involved in extending the rear axle, in that parallel lines always remain parallel even if you move them to another location. I warned him that when extending the rear axle that just having longer [upper] arms was not enough to do the job right. That in fact, what happens is the center of the forward bolting point also moves outward an equal distance to the extension. In this case, 3/4" and a straight upper arm would cause bind [unless GW knows their spherical joint can cope with the offset]. Steve said they planned a spherical front joint & a DelAlum rear bushing... I am almost tempted to make a model of four spherical joints similar to our rear suspension configuration to see if any side movement occures? I worry about it but suspension is not my expertice...

Ya'll hurry up & phone them orders to Global West so I can get my rear axle extended, OK.
George

XBOX - I'm sure that you already know this, but I will err on the side of caution. If you do the extended LCAs, don't forget that you will need an extended drive shaft as well. Otherwise, you will loose 3/4" of driveshaft spline engagement.

Do you guys know if GW will do a 1/2" extended custom instead of the 3/4"? Just curious...

Jeff,
Please phone your request to Global West: FOR TECHNICAL ASSISTANCE AND ORDERING CALL TOLL FREE
1-877-470-2975. If we get some people to request extended arms [built correctly by Global West] then they will make them. They know we need them but they don't know we will order them, their product is on the drawing board i.e., "Back Burner".

Terry,
My Dynotech is neatly hanging on the garage wall, awaiting rear upper control arms [that I feel comfortable with].<---Either I modify my BMRs [still new in box], make my own or continue waiting for Global West to get enough orders to start production...

Kind regards---George

Just wait until you do get those oem lca's off. I was shocked at how they felt like a paperclip compared to the LCA's I put on. Hope you can get them on soon!
