Lower??

[Matt Fredrikson]

Why do you need to replace rear tie rods? Do you think it's worth it to use m030 shocks or stay with the stock s gear? Yes I was already thinking bearings pads ect while doing this.

you will need toe arms. anyone who does this will.

Alingment is not the issue, it is the camber / toe settings.

the boxster's rear geometry is such that the camber and the toe settings are married so to speak.

what will happen if you dont have them is that you will have to sacrifice one or the other.

camber is more important than toe angle so that if you DONT use new arms, if you set the correct camber you will be very toe out and will chew up tires like nuts.

If you set the toe correctly, the camber will be to little and the car will handle like crap.

I used the tarret arms. You can also use the GT3 porsche racing toe arms. they are more expensive.

I bought the blue cheap ebay ones first and the knuckle was too large to fit into my wheel rims and I had to pay @ 400 for the tarret.

Good luck, and at 200+ each for rear tires, you will be saving a bundle to do it correctly from the start.

I got a killer deal on -30mm Eibach springs. So a long story short, do I have to get any other parts beside the springs?

lowering the car causes the rear toe arms to strech. The lower you go, the longer the rear arms need to be to reach the hub. My HR springs needed rear arms because the stock arms could not reach the hubs.

If you go even lower, you will need to do the same thing for the front, as well as lifting the stearing rack.

the only way to make the stock arms reach is to either really toe out, or decrease camber to zero or even +1.

I tried to be cheap, did the lowering myself, took it to porsche to align. They could not get it into specs and refused to do anything further. I said screw it I will drive it with correct camber but toe out.
I chewed up a new set of PS2, in 3 weeks of daily driving.
cost @ 450$

I got the cheap ebay arms, they where too fat, rubbed my rims.

then on the advise of the dealer, i got the tarret, fit great, alignment perfect, drives flat and nice, tires now last the standard 20K miles or so.

Amen to that:
I lowered with Eibach springs and was too cheap to get rear toe arms.
Ran through a set of new rear tires in 2,000 miles
Now with rear toe arms no unusual wear on the rear tires anymore

Performance cars are complex creatures!!
Change one thing, it effects several others........fix those, they effect several others, each..................... fix those...........

Ever wonder how Ferrari or McLaren can have dominating F1 cars for several years, each year being an update and development from each previous year and then next year, BAMM!! backmarker? They will sometimes make a change or innovation that effects so many other parts of the car, they can chase those changes for an entire year. Sometimes they have gone back to the previous year's car, while they try to sort stuff for next year!

This is something a lot of people don't understand when they modify their cars...

You think putting a stronger engine mount would help? Yeah really it does but it also make your car vibrate like no tomorrow!

There's always, always compromises...

Just ask me how I know this.
