Project Racer Part 11: Grip Addiction; We Install Progress Sway Bars
A really old photo back in my HPDE days at Buttonwillow.

Modificum Racerium – a chronically debilitating disease which is characterized by the irrationally obsessive addiction to car modification and speed. “More!” we keep chanting, as we illogically pass up hot meals for cup o noodle in order to quell this addiction by buying more upgrades for our soon to be NASA PTD car.

Read More Racing Tips From Annie!

It’s been exactly one year since we began our Project NASA PTD NX and Project Racer, and though we’ve come a long way since then, we’re nowhere near finished. But what is “finished”? “Finished” we had learned, was just an optical illusion, a line which kept vanishing towards the horizon every time you attempted to advance towards it. But now, one year later and many, many pennies poorer, we’ve advanced quite a bit, and we’ve learned that “finished” doesn’t exist. So happy birthday, little NX, you’re becoming a fine young buck.

Anyway, back to our story at hand.

Spending the last several months getting more track time has helped us learn that our little NX, fun as it was, had so much more potential to be a grip monster. Like a druggie chasing the dragon, we fiended for more suspension upgrades, more mechanical grip, so we trotted on down to The Progress Group to pick us up some toys.

My old crusty stock anti sway bars with beat 15 year old rubber bushings needed to get out of there.

Great bars and their LCA brace is the best out there. I also really like how Dave set up the end links on his (my) B13. Track-side adjustments for front or rear sways are a snap. I usually leave the front alone, but I find the rear I dial forward or back depending on the course and definitely weather. If I'm dealing with rain it goes to full soft right away.

Wow, your stock rear bar looks like it's had the crap twisted out of it by many track days.

Will polyurethane bushings still work well if your track car is still driven on the street?

Do you have before and after lap times?

Polyurethane bushings will work fine on the street, although you do give up quite a bit of comfort because your ride will become a lot stiffer, and there is a debate on how long they last for street application vs oem rubber. I personally have not had any issues with my bushings wearing too quickly.

As for lap times... i can search mylaps.com to see if I can time a before and after to let you know, but, we will be doing a before and after test and tune of similar suspension mods in a separate project car article. stay tuned!

Stock rear bar on the NX is probably no better than the pencil thin B13 one, solid steel, small diameter. With the OEM end links it binds which may account for twisting. Hollow bars are stronger, lighter, Progress doesn't have to make the rear that much larger - and for me adjustability is key. Worse though the OEM one simply doesn't work very well, tracking it tends to mangle old rubber bushings.

In harsher climates OEM rubber bushings start to deteriorate on something like 4+ years, not more than about 7 years. Specifically talking about sway bushings, LCA bushings, motor mounts. Obviously depends on mileage but I notice in New England they tend not to last 100k miles, where in AZ they would just get dry and hard, not fall apart.

Other than Poly MM's I'm hard-pressed to think of others that really compromise street ride comfort. Sway bushings take more care, the rears tend to squeak unless they get lubed every few years at least. But most of the poly bushings take out slop, which makes for smoother ride. It's probably the MM's and people going way overly stiff with sways giving them that rep. That's a huge and common mistake, running too soft springs and cranking up the sways to control body roll. All that does is eliminate independent suspension by putting a torsion spring across the car. My G was surprisingly bad that ways because Hotchis were so stiff that 150% of stock was too much given OEM spring rates.
