I have thought about something like what you have listed.

My bottom line, I want to be able to cut decent 60' times at the track. I don't necessarily need the 1.3-1.5 from slicks, but I would like to get consistent 1.6-1.7 times that an AWD car should be capable of (keep in mind, taking out of the equation driving skill, that is another topic lol).

I am not crazy about the small brakes either, which is why I am asking. But many people on the national forums said even wide sticky summer tires like star specs or others won't cut great times. Most guys recommend if you are serious about getting times, get some 17's and slicks. I was trying to find a middle ground.

I don't honestly drive the car a ton and I "could" make it into a dedicated drag car but not sure I want to. I still want to be able to do things like the mitsu cruise etc, which I will need brakes for.

For Evo's the biggest concern is the tire diameter, You want to get the biggest diameter you can so you don't need to shift to 5th to finish, this is of course with trap speeds assumed in the 120 range. 17's or 18's really don't make much of a difference in 60 ft times as Ron @ RS has shown me.

I agree with others on here about getting smaller front brakes. Especially if you can run 265 wide tires on all 4 corners, with a good tire I'd imagine you'd have plenty of traction. I ran smaller less sticky tires on my Talon when it was making ~600ish. I could spin em in first of course (plus I had non-LSD rear).

**Murlo26** · 03-20-2014

Well, I know I had TONS of traction issues with my current wheel/tire setup on my EF4 setup making 600-630whp. But I was dumping it at like 6k rpms and spinning through 1st/2nd.

So I am guessing part of that issue was driver error but it made me think I need some better tires too.

And as far as tire diameter, I am not super concerned there as I built my motor to rev, so I will just run 4th out until i pass the line, which should be 9000 or less.

I am debating about doing a final drive eventually here as well but that is future stuff. I also am not going to be making as much power as before on the next setup (most likely). I am going to target 550-600whp with stock like spool. So hopefully launching will be easier. I will also do boost by gear stuff to keep low gears at lower power to help with noobness.

At your power level, dumping the clutch at 6k RPM, be glad your tires spun. Honda guys do that to keep axles from snapping; if their tires hook w/o spinning, bye-bye axle

There is always going to be a weak-link in the drivetrain, you've already eliminated the clutch, next up is obviously the tires. If you eliminate the tires...what's next?

I guess we will find out. I don't think I should run bad tires to save other stuff, I would rather break shit and upgrade

And actually, my clutch needs attention too. At the track after 2 passes it was hot and locking me out on shifts.

Also, running it this past year to 750whp and 550wtq I think finished it off in terms of doing any racing, still fine for street driving.

I am planning on going to a twin disk but who knows when.

**Halon** · 03-20-2014

Yeah I still spun 1st on the street, and a little in 2nd. At the track I'd spin a little in first and none in 2nd. But again that was smaller tires, and straight street tires (HTRZ3's), dumping from maybe 4k, I forget so long ago haha. It's tough to find that balance, but seems like you can fit some pretty decent tires on there as is so I'd hate to settle for smaller front brakes if it isn't absolutely necessary.

Then again here I am saying that, yet I'm putting my Lexus's rear brakes back to stock (or NA supra) because the TT Supra rear brake upgrade I have installed are too big for my drag rim setup lol.

**JET** · 03-20-2014

Yeah, if you are only looking for 1.6-1.7 short times then you can do that on good street tires if you learn to slip the clutch a little. If anything you could run nitto DR's and run them on the street too. I have heard a lot of good things about the new ones.

**Kracka** · 03-21-2014

Lower your tire pressure on the strip too, that will give you a larger contact patch to the ground.

Oh, I did that, trust. I just was driving like a noob, that was the biggest issue.

Well, maybe I will just aim to get back to track and see what I can do on my current setup, with maybe some new 275's (thinking rivals) and then go from there. I should probably learn to drive better and see what I can get out of the current setup before I assume I need more traction.

I vote just go to a track and drive, then go from there.

Starting to think that is the best option and it helps its the least money. I am not spending the same kilobucks I once did on this thing, so saving is good.

**goodhart** · 03-21-2014

Won't be ideal, but by actually driving the car you will know how it reacts and what it will need by the feel of the car instead of just speculating.

Couldnt agree more

URV8SUX · 03-22-2014

Have you thought about running some like this that will allow the clutch to slip?

Evo X has a restrictor pill stock from the factory. Not sure about the guys with 6-puck clutches, but it's almost a must to remove it if you place to drive hard with a full-face disc. Removing the one from my ex-X is what allowed the stock clutch to last so long (71k miles and counting) at 425/400.

Well 71k and....lol

Yeah, that shit can probably stop. Everyone knows what happened and Hughes feels bad enough about it.

That was a joke, I have no ill feelings toward Hughes, MAP or anyone involved and wouldnt wish that upon anyone either. If it happened to me I'd expect some laughs as well. If everyone is going to get butthurt about that I'll edit my post or a MOD can delete it.
