for those of you that are doing it? How mucjh of a stretch are you running on your drift cars?

(example: 225/40 over a 9" rim)

215 on a 9!

225's fit good on 10's.
235's fit pretty good on 10.5's. my rpf1s were a pain in the *** to mount anything smaller than a 255 on so i could never really mount cool tires.



235/40/18 on a 18x10


235/40 on a 18x10.5

I had a 215 Federal on a 9 before. The Federals are built large so I think it was less stretch than another brand would have.

Thanks guys.

huh. 18" seems popular amoung the drifters. Is there a particular reason? I was thinking about running 17"x10 on a 255/45. Mostly for the look. even if it is over done, Ive never done it before. Haha Im just starting though. Any thoughts or arguments as to wich size is better to start with? I honestly wouldnt know the difference at first.

Hmm. This sounds kinda dangerous.

A 225/45 over a 9" should be ok though right?

Negative,more sidewall = less stretch ,unless you downsize the tire width. And IMHO 45's should not even be considered

How is it that more sidewall would = less stretch? I dont get that.

More sidewall == less the sidewall has to deform to meet the rim bead.

I run 215/45/17 on a 17x9 rim with fed 595's and it's barely stretched.

595's, nexen's, falken 615k, advan's, r1r's, etc are all hard to stretch because of their boxy sidewalls.

the gangster tires with the flared rim protector's look redonkulous when you stretch them. potenza's dunlops, yokohama street tires, etc.

Dude! I get Potenza RE50A RFT for free all day long from work. I have a set of 255/35 18 and 225/40 18 in my closet now. Hella meat left on them too. Just slightly used.

This makes things much clearer. Thanks!

Maybe 225/40 might be a good size foe me to start with.

^^^^^ 225/40 on what width rim???

I have 225/40 S-Drives on a 10.5, for street use on shity SOCAL roads,LOLOLO,I will get up some pics

The way the stretch looks has alot to do with the sidewall shape,& some brands/modls do not like to be stretched,they will develop a "titty" when driven hard.Because it has a soft shoulder/sidewall.

Expirence is the best teacher!!!!1

Actual FC setup question....

I ran Tein Super drifts with 8f 6r spring rates with the 13b-t. Now that I'm swapping in the LS6 would it be a good Idea to change my spring rates? Maybe 10f 7r or something? I was also thinking about adding helper springs. Any opinions on that are welcome as well.

Ask JTP about Mike Kojima. I bet he's received some pretty good insight.

(PS mike kojima has touched everything. How do you think you were born?)


edit: To post above me: I would leave the rear spring rates for sure and bump up the front a little (9k)

The LS's aren't that much heavier than a stock 13b-rew

TX hmmmmm....

.....I have been reading this thread from page 1 to page 13 and most of it is pretty much win. I have a few questions i need answered but I am afraid to post them and look like a dumb ***. Since the questions I have pertain to my GT5 FC and not the one in my driveway lol.

Everyone here has great cars and JTP is awesome for making this thread to help other drifters out there and i don't want to clutter his thread with my questions that may/may not be on topic.

TX .....................

..............do drifters do corner balancing? And what is the best Front to Rear Weight bias for drifting I heard between 55/45 and 45/55 but which one is better i don't know and i keep hearing different things and it is really confusing.

Also, brake bias is it better to have more braking force at the rear or the front? I heard it is better to have more at the rear for better transitions.

Last but not least Diff's is a 1 way 1.5 way or a 2 way really that much different and what makes one better than the other is it just the amount of adjustability that makes them good?

Any help is greatly appreciated.

s13s are good because they have a lot of front weight bias. its called polar moment of inertia
http://en.wikipedia.org/wiki/Polar_moment_of_inertia
fc's are snappy because they have a near 50/50 weight split where an s13 is like 55/45. this is beneficial to fc when it is setup correctly. makes for faster transition.

of course corner weight is good for any form of mortorsports and ideally each side should be equal.

brake bias im not sure. most cars have it biased to the front though. for drifting, im sure a near 50/50 balance would be overall best.

diffs. 1.5 way i think is the best (also the easiest to obtain for fc). a 2 way or welded diff has drawbacks since the wheels are always locked to eachother, its easier to over rotate off throttle because the tires have a harder time regaining traction.

stay with the same spring rates.. you'll be fine!

Well the S13 and AE86's are all 60/40 and the FC is 55/45 from the factory. I myself thought FC's were 50/50 for a long time till I actually glance at the FC and FD engine bay side by side you can see that in the FD it is noticeably farther back towards the bulkhead.

The brake bias thing being more towards the rear is because when you are doing tandem drifts if too much braking force goes to the front u will understeer and straighten out that is why i figured maybe it is better for it to be in the rear to slow down but still keep the car sideways, but equal brake bias could work too.


A 1.5 way locks on accel and has partial lock on deccel correct?
