235 19" fronts 345 20" rears on F430

I did in this months Forza. They said the grip was amazing.

 

Forza is a magazine about Ferraris available wherever fine magazines are sold.

 

With that width of rear tires you will probably get too much understeer. They will also be heavier so will require more hp to spin upto speed.

 

I agree about the extra weight, those really wide tires and rims will add 6 to 8 lbs per side I bet. Although they would look cool, you will feel more road harshness. I had rear 345/25 rubber on a 570hp car and it was needed and warranted with over 500ft lbs of torque but ferraris just do not need that much grip from my experience so it boils down to looks vs comfort and handling in my opinion.

 

Did you go with 19 or 20 rears? Wheels are gorgous, as is your car. I just put a set of HRE's on just this week. I have had them before and always appreicated the quality and attention to details. Enjoy the new ride and if you ever want to take a drive on the wild north coast, drop me a pm. John

 

I see lots of people putting far wider tyres on the back of their Fcars. Can I ask whether the traction off the line and around corners is noticeably better ? To what extent ?

 

I just put at 255/345 combo on mine. The rears are 20 inch. I also lowered the car 31mm. Grip is excellent and looks cool as well.

 

Are you interested in selling them? I want a set to put on my 360... PM me with a price if you are.

 

I used the Novitec springs. I did not use all 31 mm, closer to 25mm. The front end is very low. You just need to be careful when pulling in and out of driveways, speed bumps, etc.

 

I love those wheels. I was going to order the exact same for my 360 with
235/35 19 front and 295/30 19 rear. I think that combo will work.
