375HP + FC Owners what do you have for Traction?

I am looking to see what kind of traction you guy's have with what setup with a 350+ Hp FC.
If you could tell me what size tires/wheels/offsets... that would be great also what suspension, ie. lowering springs, coil-overs etc.
And with your setup what kind of traction you are seeing.
Thank You

Tokico Illumina 5-way adjust (#5 setting, stiffest) + Eibach ERS 375lb/ft (if i remember correctly) coil overs
Stock TII rims 16" with Yokohama ES100 225/50R/16

some of my friends say that the ES100 aren't the best for the money (but given they are like rougly 80 bucks each around my area, eeeh) they get Falkin tires...

well, the traction.... hm... well in a freeway, banked right turn, i can go 70-80 miles easy with minimal body roll and i feel the car grip the road... (actually by then I am the one who is scared =P)

another one, going uphill back to my house... there is a right turn climb.... lets say with third gear if u were going 30mph, your car will loose power on that climb.... (just to give u picture) so, other cars going 45mph is the limit, but my 7 can go 55 then i feel the front starting to pull to the right...

one last one.... went to some tight turns around the mountains.... the road is tight to fit about 1&1/2 FCs so i took the middle of the double yellow line turning right going downhill a bit and turned in too late... so the car's rear broke loose, and i fished tailed twice.... but manage to grab the road again.... if the tires and suspension had any less traction, i think i would have skid and died.... =)

thats my experience with this setup

I have stock suspension and Kelly Charger tires (they were on the car when i bought it and I'm to cheap to get new ones till i burn them off!)

Lemme tell ya.. that is NOT the setup you want to go with. I spin in first second AND third at the track.. I have trap speeds of 109MPH @ 14 Seconds with those tires.... They don't hook up and my 60 ft times suck ***

I'll be watchin this thread cause I'm lookin for some suspension mods myself!

Cybaster,
How much Horsepower do you have, I am talking about the kind of traction due to power, I mean putting th power to the ground sort of thing, I know people with 225's and 325 hp they can feel the car start to drift when passing at 50mph.

I was running 255/45/17 T1S's on the back of my car. 17x9.5 gram lite, don't recall the offset. In my car at 1.2 bar which is roughtly 450RWHP, I had zero traction in first. The top end of second (5500 and up) had no traction either. The very top end of third ~80MPH, I would spin the tires as well sometime.

I have zeal Function V6's with poly bushing and sus tec swaybars.

I was pretty happy with the performance, but I'm looking for a bit more traction with my next setup, so I"ll be running 275 tires under a modified body.

When I turned up the boost to 1.3 bar, I could spin the tires 1st thru 3rd all the same.

My car isnt running yet, but I will be running a streetported motor and a Greddy 25g/20g hybrid (T67) with a FMIC, Microtech blah blah blah. For suspension I have KYB AGX, Ground Control coilovers and Ground control camberplates.

Before my stock motor popped I was running the stock turbo with all the other mods, I had 17x9 Volks in the rear with 255/40 Yokohama AVS-i's. THe car would KILL the tires in 1st, 2nd would sometimes get a little loose but not bad.

I will now be running a 17x10 with a 275/40 Nitto drag radial as my street tire....we will see how it holds...

if you want traction on the street, get some 245/45 or wider (275's?) nitto 555r2 drag radials. they are badass.

I love the, "My car isnt running yet so I dont know how much power I make, or if I can even make 375+ but I have blah blah blah blah"

..

Who cares?

The guys looking for input on how to get traction with a high power car. If your cars not running, its definitely NOT a high powered car.




To help you out some though, I think one thing youre going to HAVE to get are new wheels. Wider than 225. I had 225 Nitto 555r's that I could spin in 1st and 2nd. I think somewhere down the road, Im going to get some FD wheels so I can run so 255's. I dont want any wider than that.

Where is your dyno chart? If you don't have one your car is just as "hi-power" as mine. You have no clue who I am or what I have done. I have been into this whole import thing since before you had a drivers liscences most likely and can promise you I know alot more about what I am saying than you do.

He asked what people are doing to get traction out of high power cars, and I told him one option. If I am not qualified, unless you show me a dyno chart of over 375rwhp, then you aren't really qualified either.

I am at edge with dry traction right now.

GT35R on 0.6 bar with brand new Michelin Pilot Sport PS2 245/40/17

Will see how bad it will be at 1.1 bar

due my friend has a 400 RWHP daily driver rx7 and he uses hoosier street-legal slicks that are like 265/40-17 or so... rain is interesting... but if you like drifting and don't suck at it...

Well, it's not JUST about tires...suspension is very important as is alignment. If your car is lowered (and especially if you've got coilovers) you've probably got too much camber in the rear and it's also likely uneven from side to side (a result of dropping an FC more than an inch or so in back). That camber is nice for the twisties as more of the tire will be used as the suspension compresses, but on a straight flat surface you have less than your actual tread width making contact with the pavement. I've -2 degrees in the rear and I'm running 235/45/17 sumitomo HTRV II's and I lose traction in first gear @ only 8psi around 5 grand. I'm sure once I get proper camber adjustment, that will improve. If you have adjustable shocks/dampers, a softer setting in the rear and playing with tire pressure can help with grip issues.

again I disagree
with 425rwhp on the street and always with nitto 555s never have I had a problem with losing traction in the rain. I've traveled on the highway at 75-80mph for hours in heavy rain. Of course if you want to total your car thats up to you
you'll notice a great increase in handling around turns as well...and I hear that most people get ~5k on their nittos I have 11k so far and nice tread left. Done a few long burnouts at the 1/4 mile track also.

I have Apex Springs and Koni shocks as well as RB sway bars... etc.. my suspension is pretty well setup.. the Apex Spring lower the car about 1.5 inches.
I am hopping to run 255-265's in the back... I want a 17X9 rim in the rear and the front will remain a 225.
I should be in the range of 375-400 after tunning, and want to tires and wheels to go with it.
Any suggestions?

No. My car isnt like yours because mine actually moves under its own power. I dont have any dyno charts but I know Im not making 375whp right now. I do know that I spin those tires.

Use your brain here and make the logical conclusion that hes going to obviously need more tire than I have.

Youre the least qualifided because your car DOESNT RUN!

/yourself.

275-40-17 or larger BFG TAKD, or Kumho MX is about as good as you can do in the stock body work, Brad Apold can give you the Fitments. For me traction will not be a problem

Could you perhaps get me the exact specs? I need to know if the 275's will fit in the wheels wells with a lowered car, and without modifying the wheel wells at all.
This is what I am looking for.
Plus I know that there are are a good amount of people with the kind of power I am suggesting and I want to know what they are running and in relation to that how poorly they can get traction with that power... I thought that 275's will fit in the rear, then I read other things and figured not... this is why I am asking for Rearl world things or setups that people are actually running.
Thanks Again guys... and again please keep it civil

I am sure Brad has the fitment data, try searching his posts, or PM him. The precise max backspacing on the rear on a 25" diameter tire is 6.5"(to the center of the rim), I run a 13" slick on a 16x12 with 2.5" springs, and it easily clears the spring. The limiting factor in the rear is the trailing arm, and ride height. You will have to have adjustable coilovers with the 2.5" spring, and about a 25-25.5" tire, max diameter(no 18" wheels) A 275-40-17 would require a 9-9.5" rim, so that would be a 10.5" rim overall. 6" in, 4.5 " out. Brad was running 275s on his car, I do not have a small enough rim to do the measuring, post this in the suspension section, and you will get your answer. I can tell you they will fit. You will have to raise your car a bit. CCW should also be able to give you the specs. so, take a straight edge, and measure from the fender edge to the mounting surface on the brake disc, that will give you the max dimension out. Sorry I cannot give you traditional offsets, you will either need to convert my info to offsets, or find someone running a 275 already. Carl

Even with the right offset, 275 is going to stick outside of your fenders. Thats just a really wide tire. I think youll be alright with a nice suspension, and some 255's. I have a friend with a 400+whp FD and he gets 1.6 60's doing so.
