can someone explain to me why im understeering when trying to power through a turn in second gear? i either understeer, or i dont break traction at all. never had this problem with my old car with stock shocks.
i have stance gr + pro coils kaaz 2 way with kaaz diff oil DF motor mounts poly sway bar bushings poly steering rack bushings poly subframe bushing hks 3.15" silent high power exhaust aem intake thats all i have, suspension and motor wise. i thought it was because the front was too stiff, because i had the coils set at 8, with the rear at 10, so i turned it down to 4 in the front and 6 in the rear. running -.75 camber in the front, and -3 in the rear. for some reason, my front tires just keep sliding, and there's plenty of tread on the tires. it was even understeering in the rain most of the time. anyone have a guess on the problem? theyre stock se's btw. is it just that my wheels don't have enough grip for the coils? because like i said, i didn't have this problem when i didn't have coils. if thats the case, it should go away when i get my wheels next month ya? planning on getting sbc 18x9.5 +15 rpf1's all around

it's really simple. before, when you turned, body roll would push on one side, and when throttles, it moves that momentum to the back, allowing it to kick out. Now you don't have that momentum as much, and now you are relying on the tires to make you initiate. simple fix is a) up the rear tire pressure by a ton b) buy a grippier tire for the front to allow more turn in. basically your back tires are pushing you, and because the car is now more balanced, the rear fights the front. ![]() my opinion...just buy stickier tire. Azenis 615's are perfect. |

You aren't using the full face of your front tires once you countersteer. And your rear won't break traction because once you try to countersteer the weight sways your car thus resulting in the full face contacting the ground. 3* or even more camber up front and 1* camber in rear. Your car will handle much different. For the front you want the leading tire to touch the ground at max lock. Adjusting camber in the front will help you do that.

too much negative camber in the rear. Not enough up front. Should be the other way around. But.. -3 is too much for stock se's. I'd run -1 or -1.5 with 0 or -.5 in the rear
edit: and damping - soft in the front. 5 clicks from max soft and rear needs to be almost max stiff (for stock KA) |

I noticed a long time ago that a lot of the Pro level guys have more negative camber up front than in the back which makes sense if you think about it. Run less caster too? |

I think about damping like this: Soft in the front will give the suspension more travel enabling it to grip more when initiating the car for a drift. When the rear is stiff, it prevents travel allowing it to lose traction and not grip.

you are very right. take that a step further, and now you want to add grip, you soften the rear. Or if you want to understeer more (more of 4wd drift) stiffen the front. Sway bars work the same way. As well as spring rates, tire compounds (stiffer the tire...yup). fun stuff. |

front tires = more grip while drifting. it definitely deals with more stuff like suspension set up and all that jazz but no matter what set up you are running, if you can't grip the front then you can't steer the car front tires pretty much dictate how much control you will have on your car once you start drifting, if they grip enough to allow. running a crappy tire will mean that you can understeer (when you're car moves at a more shallow angle than that of which your wheels are pointed) you always want more grip upfront than in rear, or at the least balanced grip. I'm looking into advan ad08 for the front, or federal 595-RSR, and then i just run cheap tires in the rear

I've run S-Drives, NT05s, and Toyo R1-Rs up front. The S-Drives weren't bad but aren't on the same level as the NT05s and R1-Rs. I just picked up the R1-Rs because they were 230 shipped for a pair of 235/40/17s, which was basically regular Federal tire pricing. So far I love them, it was in the low 40s at the last drift event and you couldn't tell at all.
I need to order some new rear tires. I have been running Hankook Ventus VRIIs, but it looks like they're discontinued now. I loved the way they burned, they lasted a long time and burned up evenly, no chunking or anything like that. I liked using Federals out back when I had an SR but I'd burn up a brand new pair in a few passes...and I know that will only happen faster with the LS. Does anyone have any rear tire recommendations that burn really well and are sub 100 a tire in 255/40/17?

i have a problem staying sideways.. i have shitty tires in back and falken ziex up front.. i can get it sideways(clutch kick/stage 3 clutch) and counter-steer but when i give it gas it starts to grip after a little while and catch itself. its kinda annoying im on tein he's with pretty mild damper settings. maybe i'm just being a weenie, and letting off the gas a little without noticing?

Do the Sumitomos get greasy or anything? I've slid on some random tires in the past and they got less grippy as they heated up rather then more grippy, which can suck when you expect to be able to fling the car at a certain speed only to have it come around on you when you're approaching a wall....I had it happen at VIR and it was horrible, haha. Thanks for the Nexen suggestion, I'll look those up as well. Edit: Looks like the Nexens are ~16 bucks more a tire then the Feddys after shipping, but that's totally worth it if they last way longer.

Someone earlier talked about spring settings for a KA (soft, hard).
What would you guys recommend for a good starting point SR'd S13. I normally run right in the middle of soft and hard in the front and soft all the way in the rear. |

Really?? Is it that much? What did you have on yours?
Everyone will find that sweet spot for there car. My KA S14 was 8k/7k setup with whiteline f/r sways and it was prefect for drifting and grip.

Sunny SN3800's? I don't like them. They always chunk on me.
I've used 595SS's which wore nicely but didn't last very long. Decent amount of grip. Also had N3000's, those lasted way longer than the 595's but towards the end of its life it started to chunk. Grip is pretty much non existent which for a N/A KA is not a problem lol. Had DZ101's and they smoked a bunch. Grip was around the 595's but a Tad more. Also has Process 4's which also smoked a bunch and wore decently. Grip is also up there. I'm gonna try some Falken 912's or 502's and see how they hold up. Looking for a decently priced tire that lasts and don't chunk. Gonna throw some 452's up front for some decent grip. We don't get the "Good" Chinese tires like the LingLongs, BCTs, Diamondbacks/Triangles, Achilles, etc. (As in good I mean long lasting drifting tires)
