    I’ve yet to track my 348 but really thinking hard about it. Driving on my local roads can get boring at 45 mph and where I live the twisty roads are far and few between.

    For those that are or have tracked your 348 or 355 how was it and is there anything in particular I should do to my car prior or afterwards preparing for the next. I’ve tracked a Corvette before and know the basic prep (brakes, brake fluid, oil change, stuff to take, etc.,).

    Thanks in advance for your advise and sharing an experience.

    Car prep is the same. Just realize if you're in ga. Maybe road Atlanta for you? That track is not particularly forgiving of errors. 348 body parts are expensive so drive within your limits. Otoh Daytona feels scary but really is not. After the first few laps you realize the penalty for hitting walls is high but it is actually pretty difficult because the banking is so steep, while the infield section is boring as any roval.

    Thanks!

    For now I thought I’d start with Roebling Road and the FIRM near Stark, FL. They’re both within a couple hours of me. Have you done either of those?

    I've taken my 348 to Roebling. It's a great track to "learn" the car on. Very forgiving track. I've been goiung there for almost 20 years annualy with my friends.

  5. I would set an expectation of what you want to accomplish for the day. I had a 1998 355 and still have my 1997. Same set up but alignment, ride height, and corner weighting must have been different. 1998 oversteer at the limit that would continue to come around with moderate counter steering. 1997 had under steer but very controllable.

    As you know even on any track day in any group everyone pushes. Combine that with a 355 or 348 being the most vintage model at the track days that I have done. You soon may find yourself pacing with a Miata on track tires or a new 458 or 488.

    You have tracked before in the Corvette so just set your limits. I am sure a properly set up 348 with an experienced driver does pretty well.

    For the rest of us its battling with the light weight fully set up Miata or the modern technology of the cars.

    Just like on the street the F Car has a target on its back of the guy the millennium wants to beat in his rice rocket

    Also don’t forget Barber Motorsports Park near Birmingham. Pretty straightforward track although some odd camber stuff in the first few turns. Also has an amazing museum on-site and the largest collection of Lotus F1 cars outside of the UK. And lots of art scattered about the place. Top notch facilities. It’s a pretty amazing place.

    Here’s me in the little “corkscrew” part.

    Just get out on the track and get familiar with the car
    Dont over drive it, heck first time I took my challenge car out had emergency surgery the week before and was blind in one eye, if I can do it that way anyone can LOL

    Like others said get the car set up first, alignment and ride heights so you have a good baseline

    Have fun and dont try to be Mario Andretti

    Exactly what you mentioned above has me thinking of getting a dedicated track car (though I want to experience my 348 on a track) like a C5 or C6 Vette which are inexpensive to repair/upgrade compared to a Ferrari, even a 348.

    It’s deciding what I want to do but either way the first step is just to get out there.

    Either way I think I’ll get an open car trailer and get started. Also, I’d like to drive my car through the North GA/TN mountain roads which are 5 hours away and farther than I want to drive in the 348.
     
  9. Have you joined FCA ? I did for just 1 year and they had track days and touring events. Annual 500 mile, 2 day trips included a chase support vehicle and an enclosed trailer ! Not sure what they do in your region but may be worth investigating.

    Nice benefit !

    Yes, I’m a member. I hadn’t thought about an FCA event or track day. I’ll take a look. Thanks!

    I've tracked both, and I prefer the FIRM. It has much more variety, and seems much more forgiving if you make a mistake. Roebling is fun too, but all the turns are fast and pretty much the same and if you go off course, you will be going off at a pretty high speed.

    I suggest a casual track day where there is no pressure to push you past your comfort level. Brand new brake fluid is a must, I didnt the first time and boiled my brakes lol.
    If you go, I'll try to go too, although its starting to get hot out

    Like you said on your Vette, better brake fluid and brake pads than you typically use for just the street, make sure fluid levels correct, and if you regularly track it, an alternative set of wheels and tires (I happen to have a set for sale in the parts section! https://www.ferrarichat.com/forum/threads/348-wheels-with-hoosier-r7-tires-mounted.591941/) so you dont burn-up your street tires and spend alot of time cleaning wheels from baked-on brake dust.

    If you track it often, you can also adjust your alignment and ride height settings to be a bit more track friendly without compromising the car on the street. Rake front to rear should be 10mm (with the rear 10mm higher, measured at the frame to the pavement just behind the front tires and just in front of the rear tires). This actually makes a big difference.

    Here is what I run on my 348 Challenge which is tracked regularly and driven on the street often. Thanks to Rob at DeltaVee for working with me on these:

    Always set ride height first, then set alignment.

    Ride Height in MM:
    Front: 104 mm (measured at frame just behind front tires)
    Rear: 114 mm (measured at frame just ahead of rear tires)
    Rake: 10mm

    Camber:
    Front: -1.1 degrees each side
    Rear: -2.25 degrees each side

    Toe:
    Front: 1.3mm toe-in per side (2.6mm total toe in)
    Rear: 3.5 mm toe-in per side (7mm total toe in)

    Castor to factory spec (typically around 5 degrees)

    The front to rear rake is really key. Even if you want to run your ride height higher, try and maintain the 10mm delta!

    Hope this helps!

    I race a C6 in Trans Am SGT (formerly TA3), and they are also great track cars. But i've never had an issue with people being weird about trying to "out-show" the Ferrari. Typically get compliments about it being a cool car and people are glad to see it being tracked. Key is make sure whatever group you are going out on track with has a good reputation for safety and not allowing any potentilly dangerous behavior. The steering is so great on our cars, you have to go track it to really experience it!

    Interesting thread; thanks.

    And thanks Jason for posting the geometry figures. I've just had a four wheel alignment done by my local main dealer following suspension rebuild, and just fitted 25mm spacers. I've only drive around 50 miles since the spacers but it feels more planted.

    I'm doing a track day week Monday at Silverstone, so will double check my ride height before hand.

    First track day in my 348; and cant wait. Was a passenger in a track day in a 458 a couple of weeks ago...ceramic brakes...oh my god!!

    I'll report back after my track day!

    There are a variety, but I know that Hawk makes them for this size in different compounds, as does Pagid. I'm running some really aggressive stuff from the folks that do the brakes on my Corvette Trans Am SGT car, Pro Systems, and their H21 and H16 Project Miu compounds.

    I think that the backing plate shape for our brakes is a pretty common profile, so lots of options out there.

    Thanks Jason for all the info.

    Yeah I didn’t really want to go out and have a target on my back. It’s been over 10 years since I tracked one of my Vettes a 96’ Lt4. Looking forward to it.

    Going to take a look at the track in Starke, Fl next week while on business then pick a day. I’d like to get a day in before it gets too hot.

    So, first track day in the Ferrari today. Silverstone national circuit, so fairly short. Organised by UK Ferrari club.(well organised for sure)

    Three groups, race/challenge cars then two groups of road cars, sports and touring. I did touring. 5 sessions of 20 minutes each; which was enough.

    About 16-20 cars on track at a time; which in my view was too many as the track was short so you got bunched up.

    Biggest issue was whilst I could go faster than all but about 3-4 cars in my group around the corners, most would blow me away down the straights. Big contingent of 488s and 458s, so not possibly to pass them on the straight. Most were nice and would back of a bit to let me past. Couple of lovely 246s suffered the same but more so. 200-300hp vs 600hp plus!!

    Huge range of abilities; which is what track days are all about so you just had to be patient from time to time, although a couple of wazzits were a bit too keen some times!

    Didn’t do anything special to the car before; just checked tyre pressures, wheel bolt torque and fluids.

    I did have the throttle cable come off the pedal in one session. Easy fix, but you can easily see how it can happen.

    Great fun. Had a couple of squirmmie moments, but kept it all together and learnt a good deal about the limits of my car...well past mine lol!!!

    I will certainly do another, but will look for smaller groups and or longer track.
