What suspension/wheel mods to do first? Biggest impact to driving experience?

[squiers007]

It absolutely depends on which mfr's aftermarket anti-roll bars you are buying the bushings for.

Mine are Whiteline, which are 24mm front and 18mm rear, so I got these greaseable bushings from Amazon:

Front: Amazon.com
Rear: Amazon.com

IMO, it's pointless to get the non-greaseable ones.

Both Energy Suspension and Prothane make bushings of all the popular sizes. I bought them mix because that was what Amazon showed in stock at the time. Quality of the two makes are comparable, and I would have no problem buying either brand, if I need another set.

Consensus? I'm not sure you are gonna get everybody to agree.

I can only tell you from my own experience with our two Stingers and one G70 - all running Whiteline anti-roll bars, all running stock OEM end links. We've tracked all 3 cars. If stock end links have weakness problem handling chassis loads at the limits, I would've known about it by now.

Adjustable end links are used primarily for corner balancing race cars with the (off-center) weight of the DRIVER on-board. Trying to do that on a general-purpose street car (even when tracked occasionally) is a pointless exercise.

Don't the adjustable end links allow you to adjust camber more for a proper alignment, I thought I remember reading that? Maybe this is only important if you're on lowering springs...

No

Adjustable end links have no bearing on camber!

What am I confusing them with then...? New to all of this so I apologize if these are basic questions.

Rear camber adjusted w/ the concentric washers, Front camber can be adjusted if you have coilovers w/ adjustable camber plates. Adjustable end links only allow you to adjust to keep the sway bars in a more optimum place when lowering (or raising for that matter, lol)

Adjustable end links are used to set the front and rear anti-roll bars such that they are in NEUTRAL position with the weight of the race car driver on board. This allows the bars to have ZERO torsion in the static ready-to-race stance. This is typically done as part of corner balancing process, which may also involved adjusting ride height at each corner.

That is all that adjustable end links do - nothing more.

Actually... eccentric bolts.

I think he means the longer (or shorter) aftermarket arms for the rear suspension that you can use to enhance the range of adjustment for camber. I forgot what they're called.

Just to add to this thread:

I ended up doing my suspension and tires last because I was so caught up on ECU, TCU, BEF, etc which took me sometime to save up for and install. Finally got around to doing my suspension and tires last (should’ve probably focused on all around more but turbos go psshhhh).

I got the ARK GT-F lower springs because I didn’t want the most aggressive drop on my car since it’s a daily for me too. It was a great addition and made my stock tires and wheels pop out way more and handled much better. No scraping.

The snow hit our area pretty hard and I needed new tires anyways so I went with a beefier Michelin PSAS4 front: 245/40ZR19 and rear: 275/35ZR19.

I will say of all the mods I have so far, adding the tires made my car drive like a dream. The performance mods made me fast but a little uncontrolled, felt like a rocket I needed to hold on to my steering wheel for dear life, but the tires are like the heart of the entire system imo. The rolling resistance is great and I feel more glued to the roads even in the snow! The car wants to drive straight when I test it with some gas on the dry roads.

Only con I would say about the tires is they have a bigger sidewall and make my rims look a smidge smaller, something that I definitely notice but unsure if it will be noticed by passerby’s. The beefier tires definitely add extra aggression to the car from the rear and front. Haven’t had any unintentional flats yet, pray it stays that way especially when the summer gets around and I get to smash the roads again.

Still no scraping luckily with the springs and tires.

Love my build, but couldn’t get the Michelin PS4S due to me being in a both very hot and very cold environment seasonally, and I wouldn’t survive the snowy days. When the snow started last week, I slid everywhere with the Michelin Primacy Tours albeit they were ran down but not bald.

Here she is in the snow and all before I changed tires. Can handle this weather much much better now

Where in the world are you? Flag says Aus, but snow in summer?

You mean... the Megan Racing control arms.

probably. At this point my suspension is at a happy place and I'm not going to mess with it further. it would be nice to see rear tires last more than 12k miles, but maybe I am asking too much, given even the stock suspension did the same to the first set of rears before any modifications.

The Megan control arms are really only necessary if the ride height lowering exceeds what the OEM eccentric bolts (camber and toe) are able to compensate for. Once you get beyond that, there are other negative issues at play, more than just excessive static camber.

With Eibach springs, our 2.0T rear camber is sitting at -1.5deg, which is the upper limit of acceptable range (for 18" wheel/tires), with the camber eccentric bolt maxed out. I did buy the Megan camber arms but have not installed them yet. All our 3 Stinger/G70's run between -1.0 to -1.5deg camber in the rear, and tire wear so far have not been a problem - street or track.

Also, running larger wheels with lower profile tires tends to be more sensitive to camber angle. This is yet another reason we run 18's.

Beyond that... it comes down to what tires are on the car and how it is driven.
