Tyre sizes

[colin944]

They are eibach. supposed to be 30 mm drop. More like 100mm drop.

 

[944Scott]

Mmmm i'd say can you turn the steering without the wheels rubbing on the inside of the wing/arch?

 

[colin944]

Yes steering goes from lock to lock with no rubbing.

 

[944Scott]

have you test driven it yet, does the suspension bottom out or rub in the top of the arch, also are you using standard shocks?

 

[colin944]

The car hasn't been driven for 5 years. I am in the process of rebuilding it.I know the wheels are dirty but they came from another car.

 

[944Scott]

What clearance problems do you think you are going to come up against, do the tyres foul the springs ?

 

[colin944]

I am worried the tyres will rip the wing off when I am on a fast twisty road. So I wondered what size everyone else uses on lowered cars with 17 inch wheels.
Here it is from a different angle.Excuse the fact that the car is half built and dirty.

that does look pretty low...

I use 225/45/17 all round with no issues. that's with 8j et40 wheels.

I don't think mine is quite as low - see the last page of my project thread for recent pics.

race cars will run lower, with wider tyres, and they seem ok.

I haven't lowered my car but run 17" cup1s 9" rear and 7.5" fronts (I think or could be 8") with 225/45/17 fronts 255/40/17 rears.

 

[944 man]

Are the dampers/struts new or are they older and possibly allowing the car to sag a little? Combined with a shorter spring this may be sufficient to cause the problem that you have. I have a 1988 Turbo which uses a 7.5" front rim with a 225/45/17 tyre and it is definitely more than 30mm higher on standard struts.

Hi Colin

My car is down about 60mm and I run 225's on 16" CS rims with no issues. Mine looks about as low as yours. I also have fresh GAZ gold and a stiffened ARB with the triangulation brackets and poly bushes.

[colin944]

It's got new standard struts and eibach springs. I think I will go back to standard springs or try a different brand of spring.I wanted it a bit lower but not as much as it is.I would say it's sitting very low even compared to yours Stuart and also Alan's which is on spax springs I think.

 

[Lowtimer]

Are you sure they've supplied you the correct springs?

 

[944 man]

Im confident that they havent!

 

[loc944]

It's hard to tell from the pictures, but I don't think it looks too low. I would build everything back together then see. Might be ok after cleaning wheels. Lol.
My front looked very low after fitting Design Tec -30 springs, but after rear was adjusted balanced out. Camber adjustment could also help, and even filling it with fuel.

Not far away now, get it finished.

Alan.

 

[944Scott]

How much were the springs? you could really do with uprated shocks when lowering to match the damping rate against the stiffer springs.

 

[944Turbo]

I had techart Eibach springs on my car and they were ok with 225 tyres there are 2 diameters for different years though, are they sitting ok in the the platforms?

I don't have a pic of mine on this computer and not sure I will be able to find one as it had ledas after and I may not be able to tell the difference. I think I set the ledas to the same height though - this pic i think is Leda

If you go too low you have to be carefull you dont have balljoint issues though.

 

[944Turbo]

This one is 205's with 5mm spacers

My car is nearest the camera, I may have gone up a little bit on the ledas after Peter E had his ball joint fail

[colin944]

I'm going to try a different set or go back to standard springs.I want to be able to use the car,and a few of my favorite roads are to undulating for a car that low.

 

[944Turbo]

If they are progressively wound I didn't find much difference between the standard and the eibachs - they just firmed up faster which meant shorter travel downwards meaning the sump reached a similar point as standard.
