I have seen many different 964-cars lowered, mostly by 30-50 mm.
That would be a bit impractical for me, since I sometimes drive on not so good roads, but I'd be interestd to do a 15-20 mm lowering.

Anybody has done a 'small' lowering like that? What are the best way to do it?

Cheers

Dear Christian,
Seeing as you have a ROW model your choices are very limited. You cannot get 15 mm out of the existing adjustments. You can get 10 mm so this might be worth looking at.
Believe it or not getting 15 mm is harder than 30 mm. To get this you need to use lowering spring perches which are just deeper versions of what you have installed. The trouble is that these perches move the position of the spring and sometimes, most times require the strut and shock absorber shafts to be shortened or the thread extended. This might look easy but remember this shaft is a structural load component.

Thank's Adrian, I see. So how can I get 10 mm?

how bad are your roads?? We have some pretty shocking roads in the UK and my car copes with them fine and is lowered about 30 mm.

Unless you have HUGE potholes, I doubt you will have problems.

Adrian

Dear Christian,
You use the existing spring perch adjustments. This should be done professionally because you need to corner balance as well using the last 5 mm. Put simply you lower the existing perches to the bottom of the strut and shock and then level and corner balance.

I figure they are quite similar to UK roads, so I guess it won't be a big problem. But I also want to keep an 'original' look to car. 30 mm might be ok, but I don't want the RS-look (unless I have a real RS). Do you have any sideshots on your car that you can post?

cheers

Thank's. I'll have my local OPC look into it.

not really thought about it much. I'm a phot perfectionist and currently have little time for originating a new phot and then spending the photoshop time to perfect it. I will enter a pic if I can take a good one, but I'm limited as I don't get to take the car to reall ygreat places at the moment.

PS
Noticed your car has original air box. Just got air cleaner in my service kit - but I have a cone filter. Do you need a spare??

Christian, why don't you go for the M030 springs (factory sport springs). I think they give you the lowering you want. And do you really feel the roads are that bad? I go around the city with a car which is 40-50 mm lower, and have no problems, except for some speedbumps etc.

John Boggiano

John,

Thanks for the offer but, as I don't do my own servicing and I'll be paying for one in service kits anyway, perhaps someone else can give it a good home.

Re: that picture - it's always struck me how 'matt' your sill/rocker covers appear compared to the paintwork. Presumably this is just a trick of the light?

Adrian

ROW M030 springs will not lower a ROW 964 only a US version 964.

Are they just stiffer? I've seen two cars with theese springs and they were approx 10-15 mm lower than stock. Maybe the lowering was done by just lowering spring perch.

Adrian

Fronts are the same but the rears are 40% stiffer. Do not mix up 993 or 996 M030 springs with 964 versions. I actually have a set in my basement. If you install them on a 1989 or 1990 964 the rears will actually lift the rear end up. I should have said that M030 canonly be installed on post Nov 1st build 1991 models. Special lowering perches are required for pre Nov 1st build. RUF used to sell the M030 springs with a special set of lowering perches to lower the 964 by 15 - 20 mm. I am sure this is what you saw or a version thereof.
