HGTE upgrade

Matt- If you subscribe, you can post an ad in FerrariAds above.

Your wheel's bolt pattern (5 X 114 mm) only fits the latest Ferraris (612/599/California/458) vs the older Ferraris with 5 X 108 mm bolt patterns. They might make a nice upgrade for a 612 since the rear wheels are 1" wider and 1" taller (11J X 20 vs 10J X 19 base 612 wheels), and the same width for the front but 1" taller (8J X 19 vs 8J X 18 base 612 wheels) but not sure the offsets will match. Offsets for your front wheels are 45.3 mm, and 63.8 mm for the rear wheels, I believe. You could do us all a favor and read the offsets cast into the inside of the wheels to make sure and post them. The ones I quoted are from the 20" Challenge wheels. Offset data will give a potential buyer better insight. Still hunting for offset data for 612 wheels.

He buys take-off wheel sets.

Good luck on the sale.

Hi,

Do you have the stock exhaust for sale?

Regards,

Hendra

 

Matt- How do you like the new exhaust compared with the old one?

Taz
Terry Phillips

 

Matt- Sounds great. Thanks. We need a video of an HGTE exhaust from someone eventually. Hint, hint. Sounds like it improves the sound at least as much as the HGTC exhausts on the 575s and 612s.

Will an HGTC exhaust fit an 05 612? Thanks, Don

 

Don- I would think so, but you probably should ask a dealer since the Ricambi online parts catalog I use does not include the HGTC updates. Ferrari OEM mufflers are so expensive, unless part of a kit like the HGTE for the 599, which I have not seen for the 612, that you might be better off with a Kreissieg or similar system. Ignore the wing in the photos, Kreissieg systems sound really nice.

anyone know if these wheels will fit an '06 612?

Are they still available?

 

Chet- I have been unable to dig up any offset data on the 612 wheels so far. If anybody has any, I would like to see it so I can update this list. Here is what I do have on the 599 and 612, and the entire list is attached. The 599 wheels would look nice on a 612 if the offsets match.

excellent pdf, thank you, Terry

 

Matt, are the wheels still available? Taz, would you know if the taller wheels would give me a bit more ground clearance if I put them on my 05 612?

 

612- Easy to crunch the numbers on that.

612 OEM tire sizes F 245/45 18 R 285/40 19

(245 X 0.45) X 2 ÷ 25.4 = 8.68" + 18" = 26.68"
(285 X 0.40) X 2 ÷ 25.4 = 8.98" + 19" = 27.98"

599 OEM tire sizes F 245/40 19 R 305/35 20

(245 X 0.40) X 2 ÷ 25.4 = 7.72" + 19" = 26.72"
(305 X 0.35) X 2 ÷ 25.4 = 8.41" + 20" = 28.41"

Answer is not much height gain except at the rear, where you pick up about a half inch. You can go slightly taller on the front tires, but not too much because you are limited by the 8" wheel width.

Thanks Terry. You are a genius with this stuff! May not be worth it for me then. I have a moderately steep driveway at the top where it meets the road and touched bottom a couple of times going out. No damage but it worried me enough that I am looking for solutions. I called some driveway specialists in today and they are looking at options for reducing the slope at the top. If anyone has any other possible solutions, I would love yo hear them!

612- Ride height is adjustable on the 612. If you only need a little bit of height to clear, 10 mm or so would not affect handling very much and is nearly in the normal range of ride heights. Visually, you probably could not even see it.

There is also a product that you glue to the dip in your driveway, like a garage door barrier strip, that gives you a little more ground clearance.

Terry, this is very helpful. Can you tell me a bit more? How would I adjust the ride height in the 612? Something that the dealer will have to do? Also, would you have a link on the product that I can use on the driveway to raise the ride height? Thanks again!

 

612- Your dealer, or the shop where they have alignments done, will have to adjust your ride height. Most amateurs do not have the equipment required, because both front and rear suspension alignment will have to be adjusted after the ride height change. Not a big deal on current Ferraris, which use eccentrics for adjustments. It was shims in the old days and that could be a pain.

Here is the driveway depression filler (driveway curb bridge) I mentioned. Griot's products are generally very good, if a bit expensive. Beats frequently repainting the front spoiler bottom or repairing it, though. I have one of their garage door seals, probably made by the same contractor,and it works superbly, keeping groad and water out of the garage.

Also called curb ramps, and here is another one, with a video.

Terry, thanks so much. I really appreciate all your help and advice. I'll try these solutions and let you know how things go. Thanks again!

Atish

 

Atish- Let us know how things work out.

Taz
Terry Phillips

 

Will do, Taz. I am calling the dealer today and will probably try the suspension adjustment first. I'll keep you guys posted.

 

Atish- Incidentally, Chris at Chris Customs, who handles exotics' wheels, provided me with the all the offsets for the 612, except one, and those 599 wheels will indeed fit a 612. Here are the updated data showing offsets. I am betting the missing offset for the rear 20" 612 Challenge/Monolithic wheel is the same as the 19" wheels. The bigger rear offset on the 599 wheels is due to the 1" wider rear wheels. The 12.7 mm difference is 1/2", half the 1"/25.4 mm difference.

Thanks Taz. good to know. Going to those wheels could be another way to pick up a little ground clearance then, right?

 

Atish- Only at the rear, but putting on those wheels would mean only having to raise ride height at the front a little. Wheels are more attractive to me than the 612 OEM and modular wheels, too. Do not know if Matt still has them or not.

Cool, thanks Taz. I might stay with the height adjustment for now as I want to keep the car to original specs and equipment to the extent possible. I'll keep you guys posted on the results.
