I changed the sway bars (front and back) for H&R (stiffer than the M3) on my BMW 135i and since that, it turns flat, which was not the case before. But the 135i had terrible body roll and I wanted to correct that. the handling became much better.


The 718 has almost no body roll. The sway bars are probably already very stiff. I don't see how any after market sway bars could beat that

My 718S handles amazing, even on the kinda lame stock tires, but it definitely could be improved. Depends on what the goals are but Porsche made a great compromise that's comfy on the street and fast around the track. Generally any track improvements will come at the sacrifice of street comfort and is the reason Porsche didn't do it in the first place. I've done a few AutoXs in my Cayman and there is definitely more body roll than i expected, and that's only going to increase when i go to 200 tread-wear RE-71s, and later Hoosiers. Also i have the sport PASM (x73) so other stock suspensions are likely even softer...

I will definitely be going to stiffer after market sway bars for handling improves and adjustability for tuning. The platform is very new, alot of manufacturers websites haven't been updated. The 718 has a carry over front suspension from the 2012 911, so oem or any aftermarket bar for that eras GT3 should work. The rear suspension is specific to the platform, but i don't think that different from the previous 981, so 981 including GT4 bars could work, but I'm not 100% sure on that.

I would be interested to see if the carbon fiber gt2 sway bar fits.
anything will fit given enough time and money :)

surprised to hear that, unless you are coming from a full-on track only car. i have been pleasantly surprised with the minimal amount of body roll. i spoke with some friends who race very competitively, and have been for 20+ years, and the general consensus was that hoosiers or similar r compound tires would be a waste on a car such as our with all the stability/traction control systems it has. it won't make you go faster, but it will drain your wallet faster. nt01 are more than capable of handling track duty and are (relatively) priced right.

Does anybody know if the sway bars of the -10mm PASM and -20mm SPASM are different?

Do want to keep this constructive and on topic, sorry but i do have to disagree with that, stickier tires make you go faster as does turning off the electrical nannys. Anyone that races competitively knows next to driver skill, tires are the best performance enhancer. Depends on ones goals/class/rules but if you are competitive, you want the best tire you are allowed to use. NT01s are good tires, at a good price, but they are not as fast as a hoosier, and in a class where Hoosiers are allowed there would be a performance gap. Moving from ~300 tread-wear street tire to something like a Hoosier is going to increase body roll and generally would be optimized by a stiffer suspension to match the tire.

racing is not the same thing as a DE event, by a long shot. every DE event i have participated in for the past few years has required all traction/safety systems be ON at all times while on the track. to date i have not seen anyone post about competitively racing their 718 but i guess it could happen somewhere.

everyone is free to their own opinions on the subject.

Sure thing, DEs are for fun, so performance inst an issue. I generally participate in timed events so i'm interested in performance and lowering my times. Stickier tires do that, and that's not an opinion. I agree if you are just doing DEs there is no point in running Hoosiers, thats a completely different subject as to them increasing performance.

When time allows I do upwards of 30 track days a season. I ALWAYS turn stability control off. I've never heard of mandatory use of stability management but different groups have different rules.

Bottom line is I run big Hoosier R6/7s or BFG R1s and they are a lot faster than NT01s. NT01s will be nicer on the wallet, just depends how fast you want to go.... :)

that's pretty much what i posted - with traction/stability control ON there is no need for a "race" tire, however with it off there is some beneficial qualities to their use.

Perhaps, and I'm not trying to argue with you, I'm saying traction control is not fast so why bother? It's sort of like saying, "Our DE event requires us to wear rubber boots on track so race tires aren't faster.." I bet race tires are faster either way but why handicap yourself with rubber boots (or traction control/stability management)? :)

I just received a set of bars from Competition Motorsport, they are made for the GT4 but fit 981/718s with the addition of modified endlinks for the front. Front bar is 1 1/4" and rear is 1", 5 adjustable holes each end basically matches the stock GT4 stiffness to 50 percent stiffer. The bars themselfs are top notch, not a huge fan of the bushings and endlinks that came with, but I'll end up making my own soon enough. Haven't had a chance to install them but my first AutoX is February 9th so hopefully I'll have them on by then.
