what offset do you have ?

 

WAIT A MINUTE......there is NO WAY you can stuff a 265 wide tire on a 7.5in wheel...no ******* way. That wheel HAS to be wider than you think..or you are just smoking some wicked crack.

 

i was wondering when your monster truck would show up in this thread.

 

lol that thing does look really high in that pic.

 

The stock rims aint bad.
These are 225/50-15's

 

thats what i wanted, sureshot. unfortunately/fortunately tirerack had yoko avs for super cheap in 205-60/15.

 

Well, I don't remember asking to be honest. Did I mention that other than that, my car is bone stock? Need to read. And believe me, I have had way more physics than probably 75% of the people on this board

 

"No complaints axcept I don't have enough power to break'em loose anymore."

You made a statement and I explained why...

"And believe me, I have had way more physics than probably 75% of the people on this board"

Yet you cripple your car with heavy *** rims and complain that you can't turn them over? Makes complete sense. Um yeah...

No wonder everyone runs 16's.

 

c'mon jimmy. leave the poor guy alone. he just found our performance group in louisville and we're trying to teach him. unfortunately his physics training was mainly electrical and optical.

 

I wasn't trying to be rude, but what apprears to be a crippled car to you is a nice base to start from to me. i wasn't complaining about being able to lay strips of rubber all over the place. Thta's just way to much money for me anyway. i would much rather have a car that won't fall apart in the turns than one that has a decent ET.

BTW, no need to explain anything since I didn't ask..Makes complete sense...yep.

 

I was surprised that the 265s fit on my 7.5 rims. I was worried that the tire would look bulged on the rim. However, It worked and looks fine but I would have bought wider rims for the back if I didn’t already own the 7.5s… I wanted to get as wide of a tire out back without having to buy new rims.

And yes they are 18 X 7.5 but I’m not sure of the back spacing.

 

hey man...what rims are those?

 

Well, with those rims we'll line up in parallel and end up in series. You'll be able to measure variable resistance as the distance increases between us as I'm pulling away. lol j/k man...

I just have beef with people putting huge heavy *** rims on cars that can't afford the extra weight. If you had a 20b I'd keep my mouth shut.

 

I don't want to turn this thread into a V8 RX-7 debate ......... But ..... I think I can afford the extra weight

 

v8rx7 howmuch did that swap cost you?

 

Enkei RS5's. $150 a piece from tires.com

It's all good man, but to clarify, I can't afford the weight yet. Anyone who builds a motor before they can stop and handle probably need a little sense knocked into them

 

Well, I built my motor with a fully JUNK suspension and crap tires because it was the second cheapest mod and cost me less than the purchase price of my car @ 375 bucks or so for my rebuild. (car was $450)

I had no choice but to rebuild my engine. Cracked intermediate housings don't hold coolant all that well. Cars that don't run w/o overheating aren't worth much either. Rims and tires were my last mod. I tend to somewhat agree with your statement though. However, My rims were actually less money than yours and weigh next to nothing over stock.

You're aware of how detrimental unsprung weight is to suspension performance too right? Maybe you should've been thinking about that when you got those boat anchors. They prevent you stopping as well too...

 

Yup, I fully understand what I was buying, and I have had a lot of Physics being an engineer. i found something I liek so I bought it. If later I want to try and knock a half-second or something pretty minimal off my ET, then I may look into buying something else.

As far as the stopping comment, I don't buy that it has a huge effect of it. The larger footprint and the fact that I don't have ABS pretty much outway the effects of any more weight I may add. Keep in mind that when stopping, this unsprung weight has less of an impact than under acceleration, especially at lock-up.

 

would 18s hinder drifting and should i which is best 16s,17,s or 18,s

 

What do your 16" rims / tires weigh (each)?

I will go with 16x7 or even 15x7 wheels on my 87 base when I get the $

And I still want you to explain your porting philosophy!

 

Crionics, That you state that your heavy *** rims don't hinder your stopping is simple proof you have no clue about rotational inertia. Why are lightweight flywheels bad for drag racing? Because they don't store enough momentum to accellerate the car before being slowed down.... Same thing with your wheels/tires. They're heavier therefor they take more energy to slow down. It's directly inversely proportional. Accelleration is also negatively impacted by rotational mass. Lightweight flywheels rev faster and consume less energy to spin. Same thing with lightweight anything that rotates on the car. (i.e. driveshaft, wheels, brake rotors, axle shafts) Center of mass also plays a factor in the problem with big heavy rims. The farther from the center of rotation the weight is the more energy it takes to accellerate it. (simply put, this is inversely like leveraging. Would you get more power out of the short breaker or the cheater bar?)

I bet you'd gain more than half a second if you went to a 20% lighter rim/tire package.

My 16's weigh less than the phone dials and 205/60/14 dunlaps with no tread. I haven't weighed them yet but I have two other guys who agree they're lighter than what I was running. (had them lift both new and old rim/tire setups)

You can get some crazy light 15" rims for super cheap. Like 11.5# 15x7's for $450 a set. (killer autox rims)

My porting philosophy is simple. Make the sucker breath.
