I got my MS springs and shocks today so now its time to put them in. I was wondering what alignment specs I should get? This is my daily driver but it will see about 6 track weekends (HPDE’s), and 2 or 3 autocrosses. I was able to find the following specs in my searches

Front Camber= -1
Front Castor Max after Camber
Front Toe = 0
Rear Camber -.5 more than front setting
Rear Toe= 0

I am not two concerned with ride comfort because I like the feel of the road and I have a pretty good back. Any help would be greatly appreciated.

How does it handle with 0 Toe F/R?

CosmosMpower

I have MS springs and Konis. Konis are set 1.5 turns from full soft (54%) front and rear. I think the MS springs lower the car enough to let you go nearly -2 camber in the front. If you do track weekends I would suggest a little bit rear toe in for high speed stability.

My settings are:

-1.5 front -2.0 rear
6 caster
0 front toe, 1/12th total toe in rear

Now that I think about it, the car could probably use -1.3 front and -2.2 rear, I still have some throttle induced oversteer. May need to soften the rear shocks a bit also.

Red Devil

Looks a lot like mine, except -1.4 front and -1.9 rear
can't recall caster settings
0 front toe, and a bit of rear as Cosmo says for high speed stability.

Did you have these settings in October at RA, if so how did the car handle? How does it feel on a day to day basis?

devildog1679

When you say total toe do you mean 1/24 per tire for a total of 1/12 or 1/12 per tire?

CosmosMpower

1/24th per side, 1/12th total. Normally people do 3/8 or 1/16th etc. total but the rack I used was in decimels not fractions so it worked out to 1/12th. I felt 3/8 was too much rear toe in especially since i'm running -2 camber already but 1/16th was not quite enough.

Winning 8

I got the MS spring and Koni.

0.5 front camber (min camber)
7.1 caster
0.00 toe

2.0 rear camber (min camber)
0.10 toe

CosmosMpower

Do you have a LOT of understeer with that setup plus a bigger front sway? That's a pretty big camber split front to rear. Also what do you have the konis set at front and rear?

I have a little more oversteer than I like but I would think that adding a front sway alone would take care of that, not to mention a 1.5 degree camber split with a rear gripping bias.

Winning 8

I set my Koni front 1-5/8 rear 1-1/4 from soft, I also got the RB F&R sways.
I did a lot of freeway driving, so I need the min camber I could get to save tires.
handling is ok, I could full throttle in third going on and off ramp.

Red Devil

I did have that setup at Road America, but I also was driving on the Tein Flex's for the first time so I never really felt comfortable with the car, especially having never driven RA before. Frankly, just way too much learning curve for me at once all around. I will say, though, at one point the tires broke away and I went into a full slide and the car felt very neutral before I brought it back down.

I'll be able to get back to you and give much better feedback after a few sessions at GingerMan in the upcoming months...

But my setup is:
Tein Flex
Whiteline Adjustable roll bars (both on the soft setting)
RPF1 wheels on 275/35 MXs

What should I get my alignment speced too...running Tein Flex Coilovers, putting on my Racing Beat Front/Rear Sway with an 18x8f 18x8r...any ideas? Currently my alignment is completely off and the car oversteers like crazy...wondering what i should get it set too

Red Devil

I'm getting a tire pyrometer for this summer, and should be at the track very frequently and am also getting some alignment tools...so once I start tinkering and figuring out settings I'll disclose them on the site. Though, again, my setup is different from yours, and those RB roll bars are a heck of a lot stiffer than my whitelines.

My specs are:

Front Camber -.7
Rear Camber -1.5
0.0 toe front and rear
5.6 Caster

I have the Tein S-techs with Koni Yellows(front is about 1.75 turns, Rear is about 1.25-1.5 turns) with RB sways and ADJ. endlinks. I like the setup, but I do get some push in sharp corners, and it can get a little touchy on high speed sweepers because of the 0 toe.

I think this is a good street setup also because I get pretty even tire wear and I cut down on the road noise from riding on the corners of the tires. My previous specs were -1 FCamber, -2 RCamber, 1/16 F&RToe, and 5.? Caster. I like my current setup better.

devildog1679

How did it ride with your old settings? Was that 1/16 total toe in or 1/16 toe in per tire?

marshall

Just FYI i went as much as -1.8 camber and it rides fine.


Haven't really seen much difference in tire wear either.

CosmosMpower

That's because excessive inside tire wear is from too much toe not camber.

It's good to know that 1.75 front and 1.25-1.5 turns rear causes some understeer. I was just about to take out my rears and soften them up but I think I will just increase the fronts to 1.75 and leave the rears at 1.5 which should give some pretty neutral handling.

CosmosMpower

If your car oversteers like crazy I would suggest just changing the front bar to bigger and leaving the rear stock, that should add some understeer. As far as alignment I would run about -1.3 to 1.5 front camber and -1.8 to -2.0 rear camber and run some toe in, maybe 3/8 total for the rear. Also soften up your rear shock settings with the Flex's and stiffen up the rear and you should be good.

devildog1679

OK, after hearing all the suggestions I will go with the following:

Front Camber -1.3
Front Caster Max After Camber
Front Total Toe in 0
Rear Camber -1.8
Rear Total Toe in 1/12

How does this sound?

It rode fine, pretty much like it does now. I just got more road noise from the large square rubber blocks of the tires hitting the pavement. By lowering my camber setting I cut that in half, AT LEAST. That also has something to do with the tires so your feelings might be different.

Your settings above look good, and I think you'll be happy with them.

But in saying that, I would get rid of the toe all together though. But that's just my preference. My previous setting was 1/16 total toe. It was more stable, but not horribly so. To me, the 0 toe setting twitchyness wasn't as bad as everyone made it out to be. It's only at VERY fast speeds and right at the limit. It doesn't feel like your going to lose it, it just requires you to think about what you're doing.

Great, thanks. I'll try these settings out at Road America next month and see how it feels.

devildog1679

I just got my new alignment since I put in the springs last week.

Front Camber Left -1.3 Right -1.4
Front Caster Left 6.6 Right 6.8
Front Total Toe in 0
Rear Camber Left -1.8 Right -1.9
Rear Total Toe in 1/8

They had a rough time getting the numbers to match on the camber side. Pretty cool machine they used, lasers and ****.

Targatheory

I'm about to have my car re aligned, to fix the extreme wear on the insides of my rear tires. Everything is stock, I have no aftermarket parts. And since I don't want to just give this random shop my car and tell them to realign it, what are the optimum numbers for a daily driven street car?

BlueRenesis82

i could use the numbers too, no aftermarket suspension at all, just antiroll bars
