will my new 18" rims offset my racing capabilities tremendisely ?

 

yes

 

dramatically ????..........oh well i dont believe in street racing maybe on the track i'll just change the rims

 

Yes, tremendously.

 

I'm sure MAD or myself can get into issues of heavier wheels vs light weight racing rims, 18's compared to eh optimal 16's, the force it takes to spin a 18" wheel vs a smaller one,... but to sum up your question.

yes

 

i don't think there's a difference between forces spinning man. i mean the overal diameter of the outer portion of the wheel is the same. the car does not sit higher or lower, travel faster or slower for rims up to 17'. it might seem like it but it's an illusion. when you get rims you are replacing a portion of your tirewall. the force of a 15-17' rim from the hub is nonetheless very much similar.

now the 18's. those are riduculus on tiburons. you got an 18' rim, with a 35' tirewall and 17.5'-8' width. that's just no good. good call for rubbing and a very, very hard ride. your brakes can get beat down taking all those bumps. you really want more tire to absorb shock than rim and brakes... sorry.

weight on 18's is going to just lose you so much gas and power.

 

well like I said before if I realy wana race it wont be on the street and if I race at the track i'l replace my 18" with my 16"...! smile.gif
at the moment i'm concentrated on making a show tib

 

yes there is a difference is spinning forces

ok for example spin a egg on the ground

now spin a rock

it takes more force to spin the rock

its called rotational mass

 

Centrifugal force I think is the name no? Those 18's are large, and heavy. Road Race Track cars run 17's cause it gives better grip, but with the 1/4 you are trying to go as fast as you can in a short distance. Not very good to have big heavy wheels.

 

note:my wheels are light weight maybe lighter that the stock ones i used to have ?
