Went to Tire Rack today and got the Kumho V710's mounted on my new (too me) Keizer rims. Went the with the 205 50 15 non heat cycled. Of course when I got home I had to put them on the car. I using 1/8" spacer on the rears and 1/4"on the front looks like I need to adjust my ride height a little. Front is setting 24 inches from floor to top of wheel arch, rears are at 22.

Tight fit in the rear, glad a PO somewhere along the line rolled the fender lip.

those are SLICK man!!! down right fucking SICK!

When I get the car painted ina year or two I will have to put on that clear stone guard flim type stuff on the lower fender / valance area.

Damn you can go 4 wheelin wit dat car.
Don't worry so much about the hieght of the fender lips or top of fender.

Measure ride hieght at the lift donuts. When you get her down below 4" then you got sumpin. I am some where around 3 3/4 to 3 7/8.

Thanks for the advice on ride height. I have never adjusted that before so I will get out my trusty haynes manual and read up.

Well I had to go and measure. 5 3/4 at the donuts.

Bring on the flood waters

Those tires and wheels look really nice.

Do you have adustable rear spring perches?
You'll need those if you want to lower the rear at all.

He can't go lower anyways. The tire WILL rub the outer fender and it only takes a little bit to burn the paint. With stiff suspension poly bushings I had a 3/8 " between tire and fender. 1 run and came back with 2 of the cutest burn marks in the primer. size of a quarter.

I forgot about the rear suspension as I am used to coil overs.

How much clearance do you have on the inside at the rear? If you have good clearance between the tire and the inner fender, take out the rear spacers, and you will gain the clearance you need at the rear fender lip.

You can fit the 205/50/15 right in there.

I've done it on 7" rims, so has Nathan and Grant has 8" rims.

without the spacer on the rear the rim rubs the brake caliper

Its not a problem with my fuchs, If I remember correctly the backspacing on fuchs is.... 5 1/2? The keizer is 5 1/8. Maybe its the other way around. I will check tomorrow.

Yep, Kiezer fixed that with the inserts they used on my wheels. We worked on clearences etc and they finally found an insert that would clear the brake calipers. So I dont have to use spacers.

My wheels have 5 inch back spacing and are 8" wide. They fit like a glove.

You can see the difference in the new insert here:

Well I went out and tried to adjust the ride height...I'm fuched It's is low as it can go, though I can get it adjusted up to over 7 inches from the floor to the donut

so now what I guess just run it the way it is and see what happens.

Is there specs / part number or something on that insert?

Not to be a pain the ass Grant but what is your ride hieght @ the lift donuts.

Second thing you know what I wanna do? I wanna use a Mahle center on Kiezer hoops. That would be so bitchin.

Why do I keep thinking Fuchs Mahles and Pedrini all have 4 1/2 inch back space??????

WHY do I have to put a 1/4 inch spacer on my Fuchs with Kumho V700 205/50-15 ??????
or it will rub the inner fender well. I got the marks to prove it.

Maybe my EARLY car is different way different.

Garold,

I'm assuming you are referring to your front end suspension, which is totally adjustable for ride height.

You need to re-index your torsion bars.


I quote Skline:

Remove the end cap on the torsion bar on the inside by removing the adjustment bolt and pull the end cap off and change it to give you more adjustment. In other words, if it is at the top when you remove it, put it back in more towards the bottom and then put the adjustment bolt back in. Then you will have more adjustment. You will need a jack underneath the control arm to get it out and then to put it back in.

If you're referring to the rear suspension, you need to give us more info.

Nice wheels.

My car is pretty well slammed now. I'm thinking its 4" from th doghnuts. I cant get my floor jack under the car anymore since my last lowering session. And I had same issue with my fuchs with 205/50/15's rubbing on inside occasionally. I think wider rims keep sidewalls from buldging out.

Yep I I was talking about the front.

Thanks for the info

Do you know anybody with a set of scales? I would wait until you can get the car on a set to adjust the height if it were me. It looks like in the pictures anyways, that it can go a bunch lower both front (1 inch) and rear (1/2 inch). Of course when you lower the car, the alignment is really going to change so that means an home/pro alignment and then do the corner balancing so those new tires can really do their work!

My sense is they dont have part numbers - but I'm sure Wade Huisman at Keizer will know the blank. I worked with him over the phone for quite a while. I'm sure he will remember. Its not their magnesium insert - its an aluminum insert.

Did we mention this was going to be fun? So what kind of camber are you running?
I have a touch over 2 degrees in back tire temp was 132 inside 130 middle and 129 outside and I was REALLY driving hard on fast sweeper AX course. I am going to add a thin shim and that should be about it.

Front is a touch less than 2 degrees tire temp was the complete opposite 129 inside 130 middle 133 outside. Got Welt camber plates and they are all in. Got to figure out how I want to get more front camber. Probably and

Anyway you can get more clearance with more negative camber. and them big fatty tires won't like less than "LOTS of CAMBER" !!!!

Good point, actually I do.

I made a call today to a somewhat local shop that most of the guys in our local Porsche Club use. I will take the 914 there monday and go over the whole ride height / alignment / corner balancing thing. I needed to do this a long time ago, I guess the new rims & tires finally got me off my to gett'r done.

Not much. If I remeber correctly I have just about 1 degree in the rear and someting like .05 in the front.

Well them sticky fat tires will not be any better than what you had. Cept only last 1/3 as long.
When you lower it you will get some - camber but nowhere near enough.

Sticky tires REQUIRE more negative camber or you will only be riding on the shoulder of the outside edge. till it loses grip and you are sliding is some undesired direction.

So in your professional opinion how much negative camber would be best? This is a car that is also driven on the street (granted only like 3 -4k a year at most) I would like to have something that is the best of both worlds AX & street driving, though every day I lean more towards an AX car that is driven on the street than a street car the is used for AXing.

Just last night I was trying to convince the wife that another 914 would be a good idea, this way we (I) can have the 914 for AXing & DE stuff another for the street. Needless to say she didn't buy it but she said IF we get another P car it must have a back seat for the kid Maybe a nice 1997 911 or a early 928, there is still hope <-- That's from my wife

Well not my professional opinion but a wise old man (JP) told me that -2 degrees is a good place to start for these sticky tires. fine tune from there with temp readings.

I am in about the same boat as you, I have an Autocross car that I drive to and from the events and work sometimes. 10k miles a year
I run cheap street tires 195/50 front 195/60-15 rear on Mahles. It's what I got and it seems to work.

if I had a 10 foot pole and a pile of money I "MIGHT" buy another 928. I have another teener in the garage aka. "The Stripper" I have been gathering parts for it to build a bitch'n street only car.

Hoosier reccomends -3 degrees. I have a little over -2 front and rear. Nathan was able to get more by grinding front mounting area. Camber settings will actually do more for AX slick performance than pressures in my opinion.

mine is liek ~4" to the donuts also....

205's on 6" fuchs rubbed inside fender.....

205's on 7's...not nearly as much...

but this is with -2.5 deg of camber in rear

Joe:
Your temps in the rear are just right....or as close as one gets to right. The insides are supposed to be a touch warmer.... IMO, of course.

Cool thanks JP, Now about them fronts. Got to go read the Street Mod rules real careful like. figure out if I can cut the hole bigger or just might get the weltmiester plate trimmed on the inside. Maybe a little of both.

To get one degree more negative camber, you have to move the strut mounts about .200 inboard. That's off the top of my head being as I'm too lazy to go out & do the measurements/calcumulations properly.

I'm off to Packwood, WA for an SCCA event. Practice all day Sat & the event on Sun. Rain is in the forcast for Sunday.....shit. I stunk up the joint last time up there.....sometimes you eat the bear....... I plan the shoot a whole DVD of video then bore youz guys to tears with em'.
