New Cup 2's on and before the alignment......
 
I would like to shore up the suspension without breaking the bank.

Wondering what are the best parts to start with. Both front and rear. Don't want to spend more than $2,000 on the parts for the time being. Any advice is greatly appreciated.

Stock.. unless you want to add more context around what your goal is.

RAudi Driver 07-01-2019 11:42 PM

It's stock, aligned and corner balanced. I want the handling to be more like a scalpel. The front and rear have a little more sway than I like.

Since I just shod with new tires, though now would be a great time to start upgrading some of the parts. Whether they be new stock parts of aftermarket, just though the members could offer some insight.

Monoball inner control arm piece for the fronts
RSS style 2 piece control arm in the rear with monoball inner side.. you can use a stock front outter piece in conjuction with a monball inner piece
Adjustable rear toe links with solid monoball bushings.
Optionally monoball style upper wishbones in the rear.. I reverted mine back to stock.. somehow it feels better.

This should solidify a lot of the geometry changes under load.

And yeah... maybe drop in a 10mm shim in the front just so you have more camber to play with in conjuction with the top shock tower adjustment.

Thanks for this information.

I was looking at the whole lower control arms vs the inners only. Thinking the inners are good enough for how I drive the car so there's some savings right there.

Read on the other thread about some aftermarket parts that didn't stand the test of time. Looks like GMG and RSS are good options but GMG's prices are up there. Maybe I'll take a look at what BBi has to offer.

I've gathered GT2 rear sway is a cheap, easy, very good mod

on my to do list - part is ~$500 at Suncoast

If 997.1 then GT2/997.2 GT3 rear ARB
Adjustable/monoball rear toe arms - Porsche Motorsport/997 Cup (why choose anything else?)

If wishbones are wearing, the rubber starting to delaminate, then front Motorsport wishbones with rubber inner, followed by rear wishbones with monoball inners.

Is this for the street or the track? Or both?

RAudi Driver 07-05-2019 01:32 PM

Just street and some early am fast canyons.

No trailer so no track for this puppy.

If you want to handling to be more like a scalpel, then you need to reduce compliance in the suspension. This includes any suspension parts with rubber bushings. For a budget of $2,000 you can only do so much because it isn't going to be cheap to make big changes. The tradeoff is going to be harsher ride quality and more road noise transmitted into the cabin. There is no free lunch here.
The GT2 sway bar is a good improvement. You can only do so much with alignment for street driving, but I would set the toe to zero, at least in front. Do a search on alignments to see what other folks have done. A full track alignment, with a lot of negative camber, will maximize grip on the track but it won't be usable much on the street because it will trash your tires.
Look into monoball parts, maybe starting with camber plates. You can do this incrementally as your budget allows. At some point you will realize the limitations of the OEM PASM suspension. I changed out the PASM suspension for aftermarket coilovers, which made a big improvement, but that's not cheap.
The Cup 2 tires will also make a good improvement. The sidewalls are stiffer than regular street tires so the car will be more responsive to steering input.

After looking at parts, I've increased my budget to $4,000. The car is already at "0" toe, and it's corner balanced. Not looking for a track alignment or a terrible street ride but do want a bit more than what I'm currently feeling. Going to start putting together a list. I'll post up here and maybe the members can help me sort through it.

Thanks to all for chiming in. Keep it coming.:burnout:

I have no idea what this reply even means.
