boosted DD with occasional 1/4 mi set up help.

As for the snapped axial. My buddy has snapped 2! He has way more power (600+/600+) and a 1.5 way diff in his G35. Like I said, I think the wheel hop is the thing that is killing the launch and drivetrain.

i wouldn't daily on DR's. it's a massive waste of money since they're so soft they will just melt away fast.

best bet spend money on spare set of rear wheels and go with MT ET street 2's or Nitto NT05R.

Why not just order from TireRack.com? You can order anything you want and get it delivered to an installer of your choice.

i would always get wheel hop in my RX-7 on street tires (sumitomo HTZR III i think) but when I would throw a drag radial on the back I'd hook with no hop. I got hop so bad once I ripped my trans mount out (LS1 swap).

Ive only had my Z at the track once and raced with street tires and had a lot of hop. The one hard launch I had with no hop my clutch let go. If I were to continue taking it to the track. I would upgrade the clutch, slave, and clutch line and get a set of drag radials on a cheap set of rims.

YzGyz · 11-18-2015, 03:13 PM

No No, your misunderstanding. I have a set of street rims/tires (OEM RAYs w/so4). I have another set of HR rims as stated above (rim size 19/10 with +44 offset) that I plan to put drag radials on to swap the back Rays out for drag days if the rims fit well enough. They can't be strictly Drag use only tires because I will have to drive to the track.

depends on how far the track is really. I mean if it's not really far a short drive wont destroy the tires.

I thought you meant DD on the DR's. my bad lol

Yeah, DD drags would be a big waste of $$. The track is 1/4 mi is 50 mins away. The 1/8 is 30 mins away.

yea personally I wouldn't go that far on them just to preserve the lifespan of the tire.

I have been looking and researching what rear wheels I would want (and can fit) to make a drag set-up. I would just have someone follow me with a jack and tools to swap them out at the track.

I don't have anyone that willing. That's "retarded" in there opinion. Why drive 50 minutes, help lug tires in and out of the car to watch you have fun as I sit around people stare at light, smoke and junk for hours.

Anyhoo, that;s why I think the nt05 might be the right choice. Now for the wheel hop.

If you are on stock rear arms you might run out of camber adjustment before you get to 0 camber. I'm all the way adjusted and can't reach rear camber. You might get there since you don't have aftermarket springs.

jwick · 11-18-2015, 04:28 PM

Pretty sure Johnny can get you those

Alignment and basic suspension mods and decent tires will do the job. 500rwhp isnt that bad. Its around 575+ that I find these cars to become a big hassle. Dont lower the car too much and keep the negative camber in the rear set to barely at all negative, like half a degree maybe. Get some 18x11 or 18x12 rear wheels and put Toyo TQ 315 drag radials on them. First gear will still give you a hard time on the street but otherwise it wont be too bad. At the track you can drop the pressure and do a decent burnout and get it to stick pretty well. Theres more you can do but it doesnt sound like you want to get real wild with it... 500rwhp is relatively manageable anyway IMHO. Oh, if you get a boost controller that lets you ramp in the boost as ground speed increases, that just makes a world of difference.

YzGyz · 11-19-2015, 06:33 PM

I already have those rims is the shed. That is the only reason why I even consider getting DR. I'm not in it enough to lay $$ down for a set of rims just for DR tires.

As for the Toyo, I just looked on the TireRack site and they don't carry them in the 10 wide, 19 diameter size.

As for the boost controller I have the TuboSmart Eboost street. I don't even have it hooked up right now because I don't know how to use it yet. I'm waiting till after I finish my DIY pod before I hook it up. In addition, I don't know how to wire it so that it can boost by gear or speed. I think I can do it but IDK.

RJM clutch pedal bought. Hope that helps with modulating the clutch for better launch. After that. I plan to practice riding the clutch, gas and use the E-Brake to hold the car still and launch.

I wouldnt have different drag radial wheels either, I just drive on drag radials full time. I do have a set of 15" wheels for even better drag radials that I occasionally put on though.

Ya 19" makes the tires really low profile on a car that uses such a small diameter tire. 18" would be better. Having sidewall allows the tire to conform to the pavement better and will tolerate the compression camber more when you have some sidewalls and put the tire pressure lower.

Depending on your setup, you might have to change your wastegate spring to use boost by speed. A boost controller cannot allow you to turn your boost down, only up... so if your wastegate spring is high enough that you have traction issues, you would change the spring out for a lower one, then use the boost controller to increase boost with speed.
