Tires
09-20-2007, 6:40 PM
I got an 88 lx that i was turning into a drag racer but decided to go the drifting route. Any simple-minded person can go in a straight line it takes guts to turn at that same speed. anyways what size rims and tires are u guys running. I need a clue
I just updated the car page: http://www.drift50.com/blog/drift-fox
We are running 17 x 8 -30mm wheels with 245/45R17 rear tires and 245/40R17 front tires.
Eventually with more power we may step up to a larger rear tire.
17x9" Cobra R's +20mm offset on all for corners w/ BfGoodrich KDW N/T's. 255/40/17 front and back.
I want to run some quick numbers here. Let's calculate the amount of rim space behind the hub. Basically does the 9" wheel have a negative impact on steering angle.
1" = 25.4mm
8" (203.2mm/2) - 30mm = 131.6mm
9" (228.6mm/2) - 22mm = 136.3mm
Well looks like you loose 4.7mm with the wider wheel and would therefore need approximatly a 1/4" wheel spacer when using the 9" rim.
This may have a negative impact on handling. (scrub radius)
Oh yeah, it effects steering angle. If I set my camber to -1.5 degrees I get a slight rub at full lock. If I set my camber to -1 degrees I don't get any rub. I want that extra camber.
I do have a set of longer lug studs on order so that I can run a hub centric spacer. I'm just not sure if I am going to go with a 1/4", 3/8" or 1/2".
I have the 3 sets of spacers in the garage. It became clear that I could not use any of them with the stock lug studs. Even with just a 1/4" spacer there was not enough thread for me to be comfortable.
Yeah, 1/8" is about the max with the stock studs.
i think im gonna try the longer studs. where i work we have the hanging on the wall im pretty sure no will miss them.
ARP studs are a nice upgrad for both the ben hur look as well as allowing spacer.
Do you ned to run longer studs and open lug nuts in drift events.
The 1st time I took my pony to a road race event I could not run because I failed tech inspection due to not haveing long studs and open lug nuts.
I was slightly bummed since I drove my track car up there towing a trailer with my race wheels and support equipment. I was the only pony with a trailer hitch.
i have been able to, even tho i do have extended studs an open lug nuts.. but the looked at me like i was crazy for not haveing a 4 pt harness.
I run open lugs with stock studs. You are usually fine as long as there are theads that project beyond the lug. I do plan to upgrade to some ARP studs in the future.
I just bought sum rims for a 92. They are 15 inch. I been reading your tire size so im starting to think they might be to small. I got cooper cobras and they seem to get good traction but what do i know, i just started. Once i get a lil better i plan on gettin sum more rims, what would you suggest as far as size?
The only issue that I see with running 15" wheels could be control arm clearance. Basically, do they limit your steering angle by hitting the lower control arms?
If they don't then you are in the clear. Plenty of people drift on 15" wheels.
I was wondering if there is a good tire to use for drifting? keeping in mind that just about everyone on here is on a budget I was wondering if there was a less expensive tire that still was good for drift?
Falkens are pretty inexpensive, and I've been using FK452s. Dunlops are good tires too, as are Kumhos.
Bridgestones are great but too expensive. Try to stay away from Coopers-they separate at a very low heat range. Look for tires with very aggressive treadware, and treadblock design- you want the best tire you can afford. You can do lots of research on tirerack.com
what about tire ratings? y rating, s rating, and all that jazz?
I wish I could choose my tires. I find mine in piles scattered in alleyways.
I'm with Dan, the best tires you can afford, especially up front.
Dan
What size tires are you running on the rear? I want to buy new rears, I have always just gotten whatever I can get from the used tire place, but they dont last very long and are inconsistant with smoke and wear and grip.
My rear wheels are 18 X 10. I am pushing around 500HP. I am looking for some cheap tires that will put out some good smoke.
Thanks
In the last video we were running 245/45R17 Dunlop DZ 101s.
Of course we have nowhere near 500HP, but I am guessing that the rest of your setup still has some work to catch up to the engine.
I personaly think that the smoke comes from the way you drift and how do you iniciate the drift, cause when I first started drifting I was only using power slides all the way and I got a lot of smoke (with scrap yard tires R15), but now as I reached a whole diferent level of drifting as I iniciate drift from handbrake and don't put so much power on the car anymore I almost don't get any smoke at all. And I still use R15 scrapyard tires :D
As your speed increases it becomes a lot harder to get a ton of tiresmoke. It's natural to see less smoke as you improve. To get more smoke again, you need more power and more throttle.
I have some 275/35/18 goodyear tires for the next event we are going to. They are used, but I should get a few runs. I have run these tires before and they are predictable, but the grip isnt good enough. I tried some Kumo 315's that had like a 170 tread wear a few months ago and as soon as I initiated, I would try to find the throtle position to hold the drift and the thing would keep trying to grip hard, almost went in the wall a few times. Then I have some 245/45/17 that are almost new. I have had good luck with 245/45/17 and 255's. But I have never had new ones and I only have 1 set of the 17's, I have 2 sets of the 18's. The 245 seem to be the smallest tire I can run. If I go smaller it just feels like a wet road, no feed back.
As for the setup, I just ordered a panhard bar last week. I have been bringing a full drag car to drift specs over the last year. I have improved alot, but the panhard bar, spindle modification and an Hydo E-Brake are holding the car back from greatness. I am excited for the panhard bar, because I think alot of the inconsistances with my driving stem from the rearend trying to steer.
This website has helped me tremendously.
Sorry for going off topic.
Back to TIRE stuff
As for tire smoke and initiation. I clutch kick and feather the trottle. I find that as soon as it starts the slide I have to becarful of throttle position to hold the slide. If I give it too much it spins right out. I have a wilwood drum ebrake and it works well for keeping the car from moving, but I just dont have enough ass to jerk that thing up enough to slide with it.
You are not even going to recognize the car after you get the panhard on there. It is a Night and Day difference.
OT:
Is panhard bar the first thing I should do to my car? I know it's stiffening smth, but how exactly does it get the night and day result, where will I notice the big difference with panhard?
@suo,
You inspired me to start an entirely new thread.
