| b*****e 发帖数: 819 | 15 lol, I just ordered a set of RS3 when tirerack had them on sale recently. I
have friends used both RSR and RS3, and they told me RS3 is at a different
level for the grip. RSR are very good practice tires for the price, and give
you more feedback than the RS3. RSR has good grip when cold, so basically
no warming up needed, while RS3 likes heat.
Based on my own experience of the RSR, let's say I have around 8 laps per
session, the best grip happens for the 3~5 laps, and then I can tell the
grip level drops a little, but the tires still communicate well and under
control. A set of RSR would last around 8~10 track days for me, including
driving to/from the track.
I started to run TA in our local club, so I move up to RS3 for better timing
, will try the new tires in June :)

well, I span out at a 90 degree corner at the 1st lap but not 1st session. I

Swat518,
I checked my cell phone app data, my top speed of 4th gear is 109.6, and

When you are using the RS3, what is the tire pressure before you get on
track, and what is the pressure after you finish a session?

| | | b*****e 发帖数: 819 | 21 I was looking into comparison for different tires, and found the following
useful:
http://www.s2ki.com/s2000/topic/839178-rs-3-vs-z1ss-vs-595-rs-r
Initial grip (when tire is new): RS3 > Rival = Z2 > RE11 = Z1SS > 595RSR
Longevity (wear): Z1SS = RE11 >> RS3 >> 595RSR
Longevity (heat cycling): Z1SS > RE11 > RS3 > 595RSR
End of life grip: RE11 > Z1SS = Z2 > RS3 = 595RSR
Tire feel/feedback: RE11 = Z1SS > Z2 > Rival = 595RSR > RS3
Tire feedback (auditory): RE11 > Rival = Z1SS = Z2 >> RS3 = 595RSR
Tire's ability to handle heat: RS3 > RE11 = Z2 = Rival > Z1SS >> 595RSR
Time taken to warm up: 595RSR > Z1SS = RE11 = Rival > Z2 > RS3 | s*****8 发帖数: 606 | 22 I dont know how many track days it will last, i just start using it from
this year, but i bet it wont last more than 10 track days.
I ran 32/33 cold in spring, and will drop to 30 cold in summer. it will go
up to 40. so far I found 36/37 is the better range for me, and tire
pyrometer gives proper temp reading(not the optimal reading due to lack of
camber).

| e********y 发帖数: 350 | 26 请教下 开track 的牛人们一些轮胎和alignment的问题:
1) 你们觉得max performance tire (rs3) 和 extreme performance tire (v12, dw,
pss, s04) 之间traction差距是多少?
2) 偶新买的pss 去了几次autox (spin了好几次 >_<)已经各种坑坑洼洼了, 而且感觉
直线traction没有比我原来的all season grand touring强很多. 我这儿一般是50f-
60f, 难道pss这种一定要到70f+ 才开始有超越all season的traction? (btw, 我换了
pss才知道当初hpde的牛人instructor总说我tire roll的太厉害, all season gt 轮胎
到pss的改变简直可以抵半个sway bar upgrade)
3) 我现在的alignment是 front: small toe in, -1 camber, rear 是 small toe in
-1.5 camber. 我车是fwd 300hp, daily drive/autox/很少hpde. 你们觉得把
alignment改成 small toe in -2 camber front, 0 toe -1 camber rear会不会有帮助
? 我这车以前lower过,但当时没有alignment kit, 现在新出了rear adjustable toe
rod, 和front eccentric camber bolt. 不知道有没有必要装上然后重新align下. | s*****8 发帖数: 606 | 27 我是开后驱车的,前驱的后驱肯定会有差别,我还是不做任何有误导性的建议了。
我觉得最重要的是,你是想改车还是开车(autox/track)。改车的话多去论坛看看他
们的改车的参数,和他们分享的经验。要是开车的话,所有有经验的人都应该都会建议
你从stock car开始,all season或者类似v12的夏季胎都无所谓,因为你不明白轮胎是
怎么工作的,而且也不知道它的极限在哪(我本人也没到那个水平,很难对不同的胎最
评论)。autox中的spin不是由于胎的抓地不行,是因为你操作上有误。抓地力越好的
胎越会隐藏你驾驶上的错误,而且越好的胎它的临界区域很小(比如热熔胎),不像
summer胎在快到临界的时候会响胎(这就是为什么也烂的胎在弯道越容易响胎)来提醒
你轮胎快要失去抓地力。所以在track上高速弯,用热熔胎但操控有误是很危险的。还
有就是抓地力越差的胎越容易spin,但recover from spin是一个不容易学的技术,所
以用烂胎更容易学习驾驶技术。
悬挂方面,我在还没开始track的时候就囤了很多高级货,但开始track后就一直用的
stock。当你把stock悬挂开到极限而且你知道不管理论上还是实践上camber或者toe给
你带来的影响,那时候换才更有意义(个人意见)。
我从那些有经验人中学到最重要的一句话就是,你的成绩1/3取决于车,2/3取决于驾驶
员。

话说extreme summer tire 都是热融吗?pss这种street tire应该不是吧?
hpde可以靠记忆一点点摸索entry speed, autox 则大都需要目测后直接试图push到100
%,corner entry 一旦太快就很悲剧。这种overspeed corner entry 的spin和rwd的
power oversteer 很不同吧,一旦送刹车就冲出去了。难道有啥办法可以recover?
camber 和toe主要倒不是performance,主要是为了tire wear, 我现在outer shoulder
磨的比中间和里面多1/32, 担心最后外面到3的时候,中间还是5之类的。据说更多
static negative camber 可以有效的防止shoulder wear,而前轮camber比后轮多可以
让前后轮wear的更平均,以后还可以rotate
