Thanks TrackMasters and Bob my instructor for a safe and fun event. Looking forward to going back and drinking from a garden hose instead of a fire hose. 😮💨
I guess it makes sense this could be a thing. Or I’m incorrect and this is something else. Leave it be or do I need to fish in there and clean it off?
Entering a specific turn, the vehicle usually wants to push. When it enters the turn the outside right front tire starts to make a pretty consistent squealing sound that I would say feels acceptable. And then that squealing sound starts skipping. It’s almost like when you drag your finger lightly across a whiteboard and it makes a consistent sound. And then if you push harder and drag your finger, it makes this slip catch, slip catch squeaking sound. Can you settle an argument for me here? In my opinion, when the tire transitions from a consistent noise to that skipping sound, you’ve crossed the line and are now overdriving that tire.
I’ll give you folks all the details because you seem to often need them.
2019 ND Miata on HANKOOK VENTUS R-S4 245 /40 R17 at mid Ohio yesterday. Coil overs, upgraded sway bars. Dry. Turn 5.
Anyone have personal experience between them on track? One thing I heard was the ND3 has a middle ground setting on the stability control between on and off?
MK8 R. I’m getting some kind of lighting error. Lights won’t turn off even if I cycle them “auto” to “off”. They stay on even when the car is turned off and left off for 10+ minutes. Any ideas? TIA.
I am aware there is no “1 pad solution” for street / track and I’m trying to avoid swapping pads. That said - what’s a good pad for a mk8 golf R that will spend its days as a daily and will see the track 2-4x a year. I’m willing to be sympathetic to the pads on track as in 2-3 hot laps, cool it for a lap, repeat.
My research has landed me on Endless MX72s
anything else to consider? I already think I should put in a new clutch . OE? Aftermarket? Goodwin has a lengthy warning about aftermarket "SINGLE MASS Flywheel" on the ND being hard on the semi-fragile trans.. ?
Car has 42,000 miles with a lot them being on track and autocross. Car is modified - tune (Karcepts), header, intake, catback - from what I'm told it might be +5+10 hp over stock. I've asked the guy I bought it off of if he knows if it's a stock clutch, haven't heard back yet. The for sale listing was extensive and did not mention anything about clutch and trans, so I'm 95% sure it's stock. I don't plan to modify it any further and I use it 95% for HPDE and 5% for street use. TIA!
🤷♂️ Tia!
ND Miata. Hankook R-S4 is my main track tire and the Continental ExtremeContact Sport 02 are the rain tire. The Hankooks have some tred, looks like they could tolerate some moisture. Any advice on when to switch from one to the other? My plan:
R-S4: Damp track, mist, or light drizzle with no standing water, or if rain’s expected to clear before/during the session.
Switch to ExtremeContact Sport 02:
Forecast shows sustained/heavy rain or I see standing puddles on track
Cold-and-wet mornings — R-S4 is slow to build heat, so cold + wet is its worst-case combo
If the R-S4s are already worn down — less tread left means even less water evacuation, so switch sooner as they age
Besides a pyrometer do you have any tips on how to make sure my tire pressures are correct before I see uneven wear? TIA!
If the guy in the paddock next to you asked if he could borrow your extra helmet for his brother in law to ride along with him - would you lend it? I can see an argument that lending safety equipment is a bad idea. Thoughts? TIA!
I attached all my info I think. My math says
the trailer alone is 4,240
12% of that is 508 so that’s my goal tongue weight
Truck alone is 7,080.
Here’s my question. The load increase on the rear axle from the trailer is 800.
But that’s just the weight gain on the drive axle. If I math the total weight gain on the truck from the trailer (gain on drive - loss on steer axle) that’s 580 which is pretty close to goal.
What’s my tongue weight? 800 or 580? I think it’s 580…..?
I’ve currently narrowed it down to
Hankook R-S4: seems like a community favorite for learning. I’ve read they "last forever," communicate well by howling when losing grip, and are excellent for building driver skill.
Continental ExtremeContact Force(ECF): Ive heard them Described as slightly faster than the Hankook R-S4 but with less longevity.
Do you have any additional information to add that could help me choose between these?
I have a weeping OE rubber line and was told replacing with OE is a waste of time and to go w SS. Anything I should be aware of before breaking out the credit card? TIA.
Say you have dedicated track tires and want to carry a spare wheel and tire. Can/Do you rotate it in? This would be in a RWD car with an LSD. I can already see some arguments for not doing this on an AWD car.
I guess this also brings up a second point. If I carry around 1 single spare tire and if I don’t rotate it in then if the day comes I need it, I’m going to be on track with 1 drastically different tire (wear, heat cycles). That sounds like a bad idea.
Tia!
Bought a set of Continental ExtremeContact Sport 02 for rain tires. I dont chase lap times. Any reason why I can’t run these at all my events, rain or shine? Will they tolerate 20 minutes on a +90* day on a ND2 Miata?
Again, I don’t chase lap times. I chase track time, keeping costs down and keeping life simple as in only having one set of do all track tires is nice and simple. Tia.
Safe weekend to everyone on track today. Unless you’re in Europe. Or Asia. Or Oceania. Then I hope you are having / had a safe day today.
Oh also if you’re down in Oceana, be careful and don’t drive off the edge of the Earth
