So I'm sure this has been discussed a thousand times yet when I search on my phone I can't find a single thing about it traction on a full bolt on car with meth...

Here's the deal, traction is a joke,especially coming from an Evo

The nitty gritty.. Fbo, jb4, meth, stock sport suspension (could prob use rear shocks) and on michelin ps2 rft' s'

The answer I'm looking for...
I'm not looking to have someone say get an lsd... Yea I'm sure that would help the best but out of the budget
Is there a before and after of someone's trias to find traction? Have stronger rear arms helped? Have alignment settings helped? Change to michelin super sports or maybe rt 615's
You get the point, just seeing if anyone has taken the time to maybe record 60 foot times or so after rear end mods ect

And I'll note straight line traction is my largest concern

[I'mFineW/Slow]

I'm no pro, but the easiest, at least from a thought process standpoint, way is going to be tires. Get a sticky compound and up the width even check your tire pressure and drop a bit if it seems high.

Then maybe start looking into the suspension set-ups and alignments of the guys that drag their cars if acceleration off the line is your greatest concern. Most people are concerned about suspension setups with better handling being the focus, in which case it seems maxing out the front camber is the easiest/cheapest first step, but haven't stumbled across anything about straight line traction. I wish I could say to soften the rear suspension and let the mofo squat when you punch it but I cannot confirm that is smart haha.

Hope it helped or at least gave some affirmation into what you were thinking the first step should be.

My sport suspension is shot, so that is one of the reasons my car cant handle the power. Would literally veer, mostly left, on 75%+ trottle.

This coming spring i plan on: Kwv2's, all new shock mounts, 18x9-18x10 with a 255/275 set up. Proper alignment/camber.

Along with my m3 control arms.


Will give ya an update soon.

Let me k ow what the outcome is bud!

I think k I'm gonna start with a non rft
I work for bmw so I kinda da have an infinite supply of ps2's coming off certs and tires warranty

Auto-correct.

Once you get max traction tires and all the other little stuff you'd have 50% of the improvement of an LSD and will have spent 80% of the cost.

Your Evo had two LSDs and less torque to boot. If you want straight line speed there's nothing that will replace an LSD, especially 0-60ft range.

Save up until you can do it. Otherwise you'll be wasting your money.

Get the diff lock down kit, as well for wheel hop.

1 wheel and all that torque just doesn't work. Short of 1k lb of sand bags in the trunk... But then, ya know, weight.

No not too much auto correct lol... I work for bmw as a tech (past 11 years) we get are hands on lots of patch able ps2's just not so many super sports :/

I know your right... Trust me I know the benefits of them... Only reason I'm not totally Sd on an lsd being g the end all be all is driving a stock f80 and they still feel a fully loose in the caboose... Just dosnt seem like a 3k dollar magic bullet... I ways lay twin tracks from the dsc modulating rear brake pressure just blows them loose as soon as the meth starts flowing lol

[Bmwfixerguy]

Sold on amd lsd*

[tlow98]

What tires were on the f80? If they weren't drag slicks, then they cannot handle the torque spike of sudden boost.

Good to know we're you're at tho

I recommend VWETISH kit from n54tech.com

You can have the interference coded out.

[Kgolf31]

You're never going to have Evo traction. Get that out of your head.

Toe, Tires, Shocks (compression) as well as spring rates will all play part.

And yes, LSD is a huge factor.

IMO if you don't want to do it right don't do it at all. Spend all the money on power mods and you forget the simple concept that you need to get the power down for it to be effective.

Just factory tires.. My point is that I get it and as I'm doing more research I'm finding a lot of the answers I wanted.. Like a diff lockdown wholly cow yes please lol!

I'm use to seeing completely stock cars for the past 11-12 years with different concerns, not traction concerns on there 400+whp 335i

Thanks for the input! Where can you buy his lockdown @?

Also Idk if removing it from the dsc would be a good thing or bad thing without an lsd? What's the consensus?
I do have to program my dsc for an old sib for early CBS correction, is it removed with an SSS? Like a retrofit or through black market software?

On n54tech.com in the members market section. Is going for $200.

Ask some of the guys that have done the coding. Me myself have not as I have not experienced the issue.

Thanks a lot very helpful! I'm seeing a lot of members Making a diff lockdown of sorts!

I got some nitto 555r drag radials for my car to improve traction. Sure it's much better than before, but even on pump gas I'm spinning half of 2nd gear.. A lsd will hopefully fix this issue, but for now I just gotta work with what I have

Wow Thanks bud, yea I think that will be the one I go after.. I was a little concerned about nvh and was planning on isolating it somehow if it was solid but it looks like he did a good job!

Would not be nt01r and nt05r better choice? All are rated at 100tw but nt are of softer compound. I have friends with SrT8 and ls1 that say 555r underperforms.

I got them for a good deal, much better than my all seasons I had before but still they are okay but not as good as I thought
