I am running the exact set-up Brad recommends.
It is an excellant upgrade from stock.

Koni yellow's have an infinite adjustabilty on dampening. Full firm to full soft and anything in between.

I'm using the Eibach 150# rear springs. It was very easy for Brad to lower the car exactly where I like like it, balanced perfectly with my weight in the seat.

Along with the new tires this set-up is hard to beat.
Thanks go out to Brad! (IMG:style_emoticons/default/beer.gif)

Front and rear sway bars next.

I have all but made the phone call with CC in hand for the koni setup - but whats the skinny on the rear carrera setup? Is this a bolt-on solution or are mods required? Any pictures available for this?
thanks!

Yes, you can use the 911 RSR style struts...Kanna(??) makes 'em so does SmartRacing (sweet stuff and my choice if I was to spend that kind of money !!!!)

Figure about $800(minimum) per side on the front and half that amount for the rear.

For the front, you "have" to re-enforce the front shock tower, it was not designed for the loads and forces of a coil-over from the factory.

You can adjust the stock 914 suspension pretty easy, just turn the screw/bolt for the torsion bar.

How often do you plan on adjusting the height of your car? All those "coil-over" kits they sell for the rice cars are just for bragging rights. I've got H&R sport coil-overs on my 911, never touched them in the two years I've owned the car.

The number of "clicks" also, is useless if you don't know what the rating of the shocks are.....this falls into the "dude, my shocks have 25 different settings", yea, all of them could be wrong for your car or particular setup (spring rates)
Koni

What I'd like to know is the shock dyno numbers of the Koni shock at thier lowest setting and at the highest setting. I'm sure Koni has them, whether or not they share them is another story (IMG:style_emoticons/default/smile.gif)

What type of reenforcing to the front shock tower are we talking about? I have some rust that I will be fixing and would want to get all the welding out of the way at the same time.

Any more info on it?

Also brett, what years carrera will work?

Shock tower fix

The parts can be bought from SmartRacing, it is not for your average person.

You only need to beef up the front, see Brads reply for the rear, depending on the shocks you have or want, it's pretty much 100% bolt-on (rear)

For the front stuff:
Camber Box and plate, go down to about the middle of the page.

The site doesn't really mention reinforcment. It just says "Once installed, they are very strong and allow for ample camber and caster adjusting."

Seems like it is more for adjustibility than strength. Not to mention they say that they are for a 911. (I know they will work with the 914, I am just unsure about the reinforcing that is needed.)

Anyone run coil overs with out reinforcing? What about a high spring rate on stiff shocks?

Cool! I'm below average, so I qualify, right? Right? (IMG:style_emoticons/default/mueba.gif)

Hey Brad Roberts

Have you ever gotten those 150# Eibach Reas in yet?? If so I would like to get a set.

Lou Smaldino

P.S. I tried to send you a private message and kept getting an error response.

corpselaurel ,

people have tried front coil overs without reinforcing..
sure it works for a while...

do you really want to loose control of your car when it breaks.. perhaps in a corner.. perhaps at 100mph...

not something to risk or mess around with really...
The higher the spring rate the sooner this will be a problem..


The factory design has the torsion bar act as the spring.. thus the weight of the vehicle and more than the static weight, but the increased force of hitting bumps etceterra is supported in a bar that mounts horizontally. The the Frame (if you will) of a 911 or 914 is strengthened to hold the whole weight of the car in this area below the front trunk...

so if you convert to a coil over, now you are asking the upright metal area of the front suspension to hold 2k+ when it was designed to originally only keep the shock in place...... it was not designed to hold 2000 lbs..... the top mount area will eventually pop loose... not a good thing to happen....

Torsion bars have some pretty damn good strengths going for them too.... They carry the weight of the suspension as sprung weight and not unsprung like a coil over partially does....
The weight of a torsion bar is lower..

etc...
etc...

A coil over is easier to change.. thats about it really...
the suspension joints are the same (or can be wildly modified) in either case. If your not changing springs for every different track that you visit.. then I would highly recommend against a coil over set up as the money could be better spent on purchasing seat time...

Sorry for the rant.. its been a crappy day...

What would be the best way to reduce the ride height in the front?

how low do you want to go?

at extremely lowered ride heights, you may need raised spindles, and shortened strut housings and shocks..

I have a RSR front suspension, and the shock ran out of travel at the ride height that I thought worked.. so I raised the ride height 1/2" to prevent bottoming..

I plan on having the struts and shocks modified soon..

fwiw I have #450 front springs, #350 rears....Im not to worried about the front of the car beaking..the front is quite robust... with the full depth front bulkhead etc..

this is down from the "super speedway" combo I used to have

there are torsion bar adjusters on each of the front a arms, screw one way car goes up, the other way car does down.
I believe that's all there is, others will chime in I'm sure.

I don't know exactly how low, I will need to see when I get my wheels etc. I want the control arms to sit parallel.

I was going to go with 400# front 300# rear.

Sorry for being such a noob, but could you elaborate on your setup? Any reinforcing? Do you have a link to the rsr stuff? I am searching right now.

BTW I found a link on how to lower the front.
