I want to raise my spindles, but how much ? Rich was saying 12 - 15 mm. (tho he has never done /4 struts).

Can I adjust the t. bars to RAISE the front if 15 mm turns out to be too low ?

the main reason a raised spindle becomes "too low" is that the bottom of the A-Arm contacts the inside of the roadwheel. raising the suspension ride height with the torsion bar won't help you there.

Rich also said Stock /4 spindles sit 10 mm higher. Is that the spindle being 10 mm UP the strut, or DOWN ?

I mean, if it were up, the ride hight would be lower... right ?

I got news for you. You cant raise the spindles on the 914 strut like you can on a 911 strut. the 914 strut is tapered at the bottom. You have to retube the spindle and cut threads in the top or hack up 4 struts to make two... or add tubing to an exisiting strut after you cut the bottom off.

It is no easy task. The 911 struts are not easy.. but it is simply removing the welds and sliding the spindle up and welding everything back together.

I just want to have the steering geometry to be consistant with my different bolt patterns AND wheel sizes. I have 16 x 7's which are 4 x 100, and 15 x 7's are 4 x 130...

What else can I do ? Dont REALLY want 5 lug (IMG:style_emoticons/default/unsure.gif)

Get one of those kick ass ERP bump steer kits for $300 or so. If one set of wheels is 130mm and the other is 100mm, (IMG:style_emoticons/default/confused24.gif)

if you raise the spindles on the strut, you will have to also bend the steering arms/knuckles on the strut to compensate for bumpsteer
if you don't things will be just as bad as just lowering it by the t-bar settings...

not a project for the average DIY-er if you ask me

get the steering rack spacers and forget about it...

cheers,

Dave,
raising the spindles on -4 struts is a service I provide.

You can probably go up at least 19mm, but it depends on your wheels and if they have spacers.

Brad, correct me if I'm wrong, but don't the Boge 911 struts have the same diameter change in the tube as the 914?

I know the 911 Bilstein struts are one diameter.

What about original Koni struts? I don't know them at all.

WOW Chris !! I may be up for this, afterall...

On the 15's, gonna run 1" spacers all around. On the 16's, 5/16" up front.

If you can, the best thing to do would be to install a wheel onto the strut with whatever spacers you will be using, then measure the clearance between the ball joint collar and the inner surface of the wheel. That way we will be sure they will still fit after modifications are done.

Front susp. is officially removed. So, I guess I will be waiting for a while before it needs doing...

Here's Geoff takin' the A-arms off earlier...

Correct James. The Boges are the same as the 914 Boge. The Bilstein/Koni/Later Carrera Boges can raised "easier". Most people dont use the 911 Boge to do anything.. so I rarely make any references to them.

Bilsteins are easiest. They have a straight tube.

Both of my Koni's (911 and 914-6/GT) are raised 18mm. This is the max. you can raise with a 15" wheel. This is also the max. you can raise a Koni (without performing some of the magic Chris is capable of). Koni's have a similar "buldge" like the Boge's but there's is 18mm to play with. There is no room on the Boge. Here's a picture of my Koni's being primed showing the "buldge" in the tube:
