10.5, i didn't go for 12 or 13 because it will be more heavier and i will use wider tires and this cause a seriuos lose of the power of the car, by the way my car weights after the modifications 1633 KG

 

There are 12 and 13" wheels out there that are lighter than the 10.5 you have on your car...but they are very expensive.

 

With the amount of hp you are laying down, I would think that getting the tires to hook up using 285s is going to be a much bigger issue than the weight of wider wheels/tires, even at 12 psi. What is the lowest gear in which you can give if full throttle without smoking the tires?

I have 305/30 Toyo R888s going on the back of mine, but if I had a wide body kit and the room to go wider, I would do so. But that's me.

Nonetheless, it's your car, so you have to do what makes you happy. So take anything we say here with a grain of salt.

 

how much is gas a gallon in S.A?

 

lol, very cheap and 95octane at pump. 15 gallons for like 8 dollars

 

It's my pleasure to read all your sugestion, i take it in my mind and it will help me to improve my car.

My differantial in my car is the automatic which is very long,when i replaced my automatic gear to manual gear i didn't change my diff which give me long ratios in my car, from the second gear from 70 i don't have any spining in the tires and i change by 8000 RPM or by 8500 RPM if there's a strong car racing me, at 8000 RPM in the third gear if i shift to the fourth my speed is about 190KM.

 

For 1 liter from the unleaded fuel 95 Octane it cost $0.16

 

 

I agree you should get the widest tires so you can put the power to the ground. I have 20x10.5 w/ a 275/30 the 3.3 gearing and it still doesn't grab at all, but looking to get wider next time. Having so much power is basically useless if you don't have traction.

 

Nice work on the G though that's a list of mods there. Only thing I don't feel is the rear wing should of went w/ something a little more subtle

 

I really am starting to like that body kit. Nice mod list

 

 

Holy revive thread batman!

 

Newbs....I guess he can search anyway
