What did you do to your Kia Stinger today?

[Buzzman12]

Actually, since I don't have anything behind the front seats, except for the carpet, I'm brainstorming the idea of bracing b-pillars to driveshaft tunnel.

Sounds like a roll cage. Do it. That should stiffen things up.

For a hatchback/fastback - with such a large rear opening in the unibody - loss of torsional stiffness is the biggest concern when it comes to structural rigidity. It does not help that rear opening is directly over the rear axle, where the forces acting upon the rear of the chassis will come from. Easiest way to visualize this is when one wheel hits a large bump and deflects that corner of the chassis upward. This contorts the chassis and can lead to adverse handling responses, if the chassis does not have sufficiently torsional rigidity.

This is why you see a lot of mfrs will add stiffening braces between the rear shock towers/wheel wells. To be of any use, such braces need to be triangulated, which is why you often see an "X" brace. Adding a top cross bar to the "X" is also helpful as it turns the brace into a full lattice frame. However, adding just a straight cross bar would only resist tension, or maybe a bit of compression, but do little for torsional stiffening. If such a crossbar is added below the chassis to the underside of the floor pan, it would do even less good, as that cross bar would see little tension/compression strain - especially since it has to hug the floor pan very closely. It would help nothing for the torsional load the chassis is likely to be subjected to.

For a 2-door coupe sports car, the B-pillars are often right over the rear wheel wells, so bracing there makes perfect sense. However, on a 4-door sedan, bracing at the B-pillars is less effective in resisting chassis torsional strain, since they are typically near the center between the front/rear wheels.

FWIW, this is also why the G70 handles noticeably better at the track than the Stinger, even though the two cars are very closely related and share the exact same suspension. Stinger's 3" longer wheelbase makes a bit of difference, but it's G70's rear crossbracing - typical of a sedan body - that makes the most impact. Driving ours back to back, the difference is definitely noticeable.

Thanks! That is informative reply. I was going to brace the rear wheel wells area at first. But I realized that just one flat bar wouldn't be doing much. And if I connect it to the floor area that woud decrease my trunk area. I load a lot of stuff from time to time in there. I guess I have more thinking to do. You think something like that should do.

Either method would work. I have seen it done both ways.

Most of them are mounted just behind the rear seatbacks to maintain as much trunk space utility as possible. The attachment points are just as important as the design of the cross bracing. Sometimes, stiffening plates need to be welded to the trunk floor to spread the stresses imposed by the cross bracing. Also, just because there are convenient attachment point don't necessarily mean they can be used for structural bracing. Again... just because somebody makes and sells something... doesn't mean they actually do what they claim they do. I pity the fools that buy into these stupidities:

There's reinforced area where rear seat belts bolt to. I think that should be the best spot for the upper section. For the bottom, you are probably right, some plates will have to be welded. Will just have to figure the way to position the bars, so I still have the option to carry 10feet 2x4s. Gotta love that stinger versatility.

I just changed the cabin air filter @ 15k miles. It’s super easy!

I updated the navigation in our 2019 Premium. It looks identical to the interface/theme in our GT1 which I installed two years ago. The update took less than half an hour of pleasant driving on Mountain View Corridor. Went all the way to the south end, by which time the update completed. Swung into a one-eighty back onto the highway northbound and, having it entirely to myself at the moment, I gave it WOT and took it above a hundred for the first time, to 111 MPH, then backed off and coasted past a couple of vehicles in the righthand lane, then moved to the right lane myself. The next car ahead was a black sedan - make unknown to me, but maybe one of you can tell - the wheels are Stinger GT-like. It was ahead a couple of hundred yards, when suddenly from the left side a silver pickup truck appeared crossing the highway at speed. And the sedan driver only had enough reaction time to yank the steering wheel to the right and then impacted the passenger door and RF fender of the pickup. The truck spun out to the right and ended up a full one-eighty facing the opposite of its original direction and off the road. The sedan bounced off the truck then continued in a righthand spin and ended up facing a full one-eighty to its original direction, straddling the middle of the cross street. All three involved persons, the pickup driver, and the man driving the sedan and his woman companion, staggered/crawled out of their stricken vehicles, and the two sedan occupants laid down on their backs beside their dead car and moaned. The driver was clearly beat up, the woman not as much. The pickup driver was on his feet and only rattled. I had pulled over to witness for the cops when they arrived, and called 911 and said yes to the question, send the paramedics. I talked briefly to the pickup driver and he said that he hadn't seen the stop sign and wasn't from around here. Paramedics put the sedan man in a neck brace and put him on a stretcher, which maneuver caused him quite a bit of pain. His gal, from where she was still lying face up on the pavement, said, "They've got you, baby" a couple or three times. I filled out my witness report, snapped a couple or three more pictures and headed out.

Man, that was a close one! In another handful of seconds, I would have been in that position to get T-boned or do the T-boning myself like the sedan driver had. A merest fraction of a second difference in his position and he would have been T-boned and likely dead. If I had held my extra-legal speed up to 120+ MPH, that could have made all the difference in the timing, etc.

I did the same this morning... cabin air filter was nasty. Replaced it with a STP brand.

Could you share a link for the cabin air filter? I needed a change too. I checked Rock Auto, they have the WIX brand as well.

 

[xaviersayys]

obligatory “washed and waxed her” post. first time though in like almost 3 months since it was raining every single week. nothing like a fresh coat of collinite 845.

Got mine from the local Autozone.

My previous car, the Mazda 6 which I sold to a dealer two weeks ago, has now been listed on their website.
It was a nice car, well maintained by me. The pics look nice.
Last year when I bought the Stinger, someone on here said at the time that my Mazda wasn't worth more than about $11K, and that I was nuts for wanting more. Well, here ya go.

First post! Excited to join the forum. Today, I added the modern kia badge replacing the 2019 version that came with the car.

 

[street heat]

So after my last stinger was totaled im back in a new one. already painted mirror caps matte black, added a spoiler, threw the rear niche misanos from my last car on, added mud guards, and front lip. Today i put on the alternative lettering. There is still more modding to do but im loving the way its coming along.

Cool! That was quick. When you say "new one", you mean new to you, am I right? You didn't pick up one of the last c. dozen brand new Stingers still in the country?

Ran mine at Import Face off Rockingham, NC 11.5 index. Crushed the soul of this Supra
