It's not like the ZL1 comes equipped with off-brand all-season tires (Mastercrafts, anybody?). If anything, maybe wait until past when you're absolutely sure that it's the tires holding you back instead of it being the other way around. Norm

I re checked my notes and realized I actually didn't find a lot of into on how well the Hoosier R7's compared to the SC3R's in terms of durability/wear or grip/performance

Totally agree, that's the plan.

EXCELLENT POST TRACK CLUB!
Bottom line is safety mods first and then lots of seat time. Along with seat time, tires and brakes should be the only mods on your mind. |

One other thing to consider when running slicks vs a 240TW street tire (GY SC3) is the other setup changes that will also be required to get the most out of them:
- Brake pads and fluid, stock pads are arguably ok for the stock tires, once you go to a slick you'll definitely need something with a higher temp window - Alignment settings, you'll probably want more neg camber (camber plates) - Different tire pressures than stock (need a tire pyro and time to get them sorted)

I was lapping 2-3 seconds a lap faster in the SS 1LE on 200 tread street tires than his C7Z buddies on slicks. I think that data point convinced him to keep his car stock for now, plenty to learn still. |

OP: I posted another response last night, but later decided to delete it, as i had started repeating myself (perhaps old age lol?). Bottom line, it is clear from your responses that you get the jist of the matter and then some! It is always a pleasure to converse with other open minds - so to this end - thank you! Cheers! |

However, I would not at all be surprised if those JRi dampers, when setup, are worth 1-3 seconds a lap consistently at Sebring over MRC. I'll be having to enjoy this process with the rebuilt BRZ which is running some 2 way dampers later this month.. but once setup it'll be good until other changes are made.. Even when switching tracks I generally don't bother to retune it since it's just a DE car and I don't want to spend sessions gaining a few tenths.

At events I help run we won't allow novice or intermediate students to run R comps (or anything higher end of course like FIA slicks) for this very reason.

Shock setting is a complex art, one that requires high degree of driving skill to define what the car is doing well vs not in each phase of a corner, moreover differentiated into slow and fast corners. If a driver cant tell this, then any set up change is just a game of guessing. Moreover, one needs to understand what will actually happen when changing bump or rebound rates at each car's corner vs just turning knobs and hoping for the better not undrerstanding causes and effects. Trying extremes and then - likely - landing on a happy medium, will - likely - brings one back to a good factory setting, more or less. So what's the point? With 2 way adjustable shocks one already has several possible permutations of settings available. Add adjustable sways to the equation and the number of choices jumps up. Add multi adjustable shocks and the picture really gets complex. Pro crew chiefs have written books on this subject and for a very good reason. Lastly, buying an adjustable suspension and leaving it static regardless of track venue, conditions and other variables is pointless imo. Thats exactly the same end result as having a fixed suspension. As far as camber, Provoste runs scrubs and i dont think his camber is overly excessive. My memory tells me it is less than 3F but i may be incorrect here. I ran slicks with 2.6F on my Vette with zero issues. But thats a different platform obviously and it also depends on width of tires. Isnt it fun being an arm chair expert? Lol! Cant wait for the spring! Best of luck with your new project. It is clear that you are knowledgeable and capable - so enjoy it and have fun with a new toy! All the best! |
