You're running a tire with a lot of mechanical grip and even though you have a lot of negative camber, running too soft a spring rate without stiffer anti-roll bars will allow the car to roll sufficiently to compromise the geometry and destroy the tire. You may also be running too soft a rear spring rate relative to the front spring rate, causing the car to have excessive understeer and destroy the front tire. What's the overall balance of the car like? Lastly, the RE-71R is better suited for autocross than DE or extended circuit work, so maybe you're just overdriving the tire.

I ran the pro and the long track configurations, the pro track is almost exclusively composed of right turns and a lot of them are high speed. So my question to you is, what suspension setup do you have (spring rates + dampers + ride heigh + sway bars)? As a reference, I had a bit more wear outside than inside in both rear and front and im running 6k/8k spring rates, on very stiff damper settings and stock sway bars. My camber is -3.8 front, -3.2 rear, -0.1 toe-out front, 0 toe rear. Running RS4 tires, which should have similar grip to yours (maybe a bit less when yours are not overheated). |

Thanks for the reply. Im running Tein Street flex 7k/7k. I am actually running Eibach sway bars all around. Both on full stiff settings. The car DOES tend to understeer more than oversteer on throttle. Could it also be my driving? I feel like O go in to hot into a corner, resulting in the tire scrubbing of speed. Im probably wrong |

Awsome! I was actually there this Saturday too running the long track. I guess you guys were the group before us! I listed the specs above about my car. passenger side tires had even wear. My driver side tires especially the front had A LOT of wear on the outside. I had about 30-40% tread life left coming into the track day. My driver side especially, the outter is basically completely worn with no tread left. |

Guys enlight me, i want to lower my car and im considering yellow springs on my stock shocks but the shocks have 63k miles on it, i commute 44 miles a day 35 are highway the rest is backroads. My concern is, can i install springs and lets say the shocks will last until 100k miles on new yellows or is prudent to buy coilovers instead? I want to keep on budget and coilovers are overkill for me but i seen some coilovers of Tein (street basis z) that fit my budget.

Last thing, dont expect RE71R to have any kind of decent thread life. I've seen people go thru a brand new set in 1 single lap day. Usually the more demanded tire ends up bald at the end of the day. Those are autox tires, or 1 lap wonders, they dont really take prolonged heat well. |

Thanks for the advice! I run my dampers max rear and 2 clicks away from full stiff in the front. My sway bars are both at full stiff. I will adjust my front sway bar . The car does push a lot going into a corner I feel. |

Another n00b here with very little suspension knowledge (I have been reading!)
Budget $1500ish or lower. Goal: DD 95% of the time, 5% spirited driving with possibility of an autox once on the coils. Drop: less than an inch never more due work speed bumps already scraping stock setup. Think LA but better. Tires by end of this year: MPSS 245/40r17 Probably SPC LCA unless I can be convinced otherwise. I was looking at Tein Mono Sport, is this too much for a DD car? I was also looking at the Flex A. Goal is more OEM+ than track monster, needs to pass the GF test and lower back test. Taking other suggestions, from what I've read this budget isn't great 2-3 years ago.

Can't go wrong with a Bilsten B6 and RCE Yellow combo since you're not looking for much of a drop. Performance will be greatly improved with very little to any added harshness compared to stock. Get some camber bolts up front and those SPC LCAs and a mildy aggressive alignment and you have a super solid setup that will be perfect for a DD that will be in your budget. I'm sure the other guys would agree. |

Would Flex A be harsher or less sports oriented? Flex A is still mentally on top due to top hat included. How about the B14 (on sale now) with some Velox top hats? Similiar Comparason for anyone else looking. Great suggestion, didn't even think of B6/B8's + RCE Yellows. Thanks.

He may wish for more camber then with bolts-only.
