factory setting is a good setting to start with, the factory put endless hours and engineer behind their alignment to give you the best result on the road and on the track. if you lower your car you could go and do a toe set to 0 toe in front and 1/8 total toe in on the rear to start with, and keep the caster and camber as it is. just balance out the camber and caster if it came out uneven.

Dear all
Would appreciate all on my suspension settings.... Currently going for the occasional track day and used as a daily driver Suspension (Front: 11kg Rear: 4kg) Camber (Front: 1.5 Rear: 2.5) Toe (Front: slight toe out Rear:slight toe in) Castor (Front: 6 deg) Tyres: 225/45/18 AD07 Thanks in advance for your input Alan |
i am going to make a simple statement here.
the #s in the first post are a great place to start.. and when you get good enough to move on you will know what to do.. i am talking about track settings, with real sized tires and offset. if you are running 275s staggared with a 2.5 camber. you have missed the point of this thread.. beers :beer: |

Those are some unusual spring rates. Are you running stock swaybars?
The spring rates are very unusual but it provides easy traction when you power out early in the corner as the rear squats much easier according to my friend..... |

sorry, can you clarify what do you mean by balancing the camber and caster if it came out uneven?? |

My guess is that your car will understeer. I'm not sure what impact the much softer rear springs will have though. If it understeers I would bring the camber closer together and set the rear camber slightly less than the front.

Once again, thank you all for the input |
the first post was about a track street setting. and it works very well on the track for many..
you are so far away from it.. the spring settings are odd. you should be asking local track only cars for help. where are you? you are way outside what this thread is about.. beers :beer: |

By the way, I am in Singapore and the track some of the local guys go to is Sepang Circuit Cheers |

beers :beer: If you're going to run that much spring rate differential you'll need to swap those camber settings |

Here is what i'm running for daily plus track and mountain
Suspension (Front: 8kg Rear: 6kg Megan Coilover) Camber (Front: -3.0 Rear: -2.5) Toe (Front: slight toe out Rear:slight toe in) Castor (Front: 6 deg) Tires: 255/40/17 NT01 |

If you're going to run that much spring rate differential you'll need to swap those camber settings Are you suggesting that I should run more camber in the front vs the rear for more oversteery characteristics?? I generally worry about opening too big a camber in front cause I understand it will affect my braking....alternatively do you all adjust the castor to add camber during conering? Cheers Alan |

Cheers Alan you have a Renesis, not a fire breathing V8 LS1 engine, hooking up on corner exit due to power isn't an issue for an RX-8 unless you've swapped on a FI system, the rear also gains camber under compression I'm not big on front caster, I would place emphasis on setting optimal front camber first, then run whatever caster you can at that setting if it matters to you IMO the only reason to run a higher rear camber setting is if you have soft front bar/spring rates (read:weight transfer) because then the resulting net body roll has to be compensated |

but you're worried about the rear hooking up off the turn, yet want to run all that rear camber :squint:

If you need it as a daily driven, I will not go over -1.8 degree camber front, -1.5 on the back.
anything more is an over kill, and wear out the tire faster. toe out in front also wear the inside tire faster, so I keep it at 0, and 0.08 toe in each side on the back. |

Yo Alignment buffs! I've read this thread and others here and can see there are lots of good suggestions and discussion about the best alignments, etc. for different situations.
I want to stop the uneven wear on my tires as shown by these NT-01 R-Comps. Any of you that have been there / seen this... then changed things for the better... please tell me how to adjust alignment to change this wear pattern, assuming it's not just inevitable because of track use? OK, here's my alignment/corner balance w/my weight in the seat. Attachment 280228 Here's what my NT-01s I look like right now. This is a bit over a year old set used for I'd say 38 1/2 hr track sessions, plus ~2500 miles street driving getting to and from. They're still track worthy, but are getting ready for replacement. Now admitedly I work at wearing them down as often as possible... http://i240.photobucket.com/albums/f.../tirewear1.jpg http://i240.photobucket.com/albums/f.../tirewear2.jpg Attachment 280229 ...but as you can see (I rotate them often) the wear is even, but at an even slant going towards the outside, then accelerates at the edges. From what I been reading here, more camber than what I run means uneven wear, but it looks to me like more is needed to get the inside wear rate up! Other setup... Whitline sways at medium front and rear...no overriding under/oversteer, and as far as I can tell cornering stays flat. I run 36-38 cold, 40-46 hot for tire pressure, depending on ambient temps. Before buying new tires, that might be softer and so wear much faster .....I'd like to get this under control. What do you think i might change? |
It's crazy how fast the 8 would turn in with a good alignment. I had the luck of getting mine aligned by a guru here in Austin. I think I still have the alignement printout here somewhere.
I miss it. That ass end would load up and break away pretty easy if you didn't know the way it wanted to be driven. |
