custom coils (coilsprings.uk)

so i found a company to make me custom coils for my 97 saab 900.(coilsprings.uk) and i would like to keep the suspension geometry that of a saab viggen but slightly lower than a stock viggen. so my question is what amount of lowering do i need to do to achieve that? i know that in the ng900 the suspension sits higher in the rear and that is my main concern to level things out more like the viggen suspension. i was thinking itd be something like a 40mm drop in the front and 50mm in the rear but im not quite sure what will give me the look i desire. anyone know the difference in suspension from a viggen to a ng900? if i can find the difference i can know how much lowering will make my saab a viggens height and from there i can lower as needed!
thanks

jeff

Stock viggens sit higher in the rear too.

There are 10's maybe 100's of threads on here comparing various spring setups and combinations

Vogtlands are almost too low for the NG. They could benefit by being 10-15mm higher. They only provide a short range of travel before your riding on bump stops.

I'd like to try the eibachs, but they need to be imported from europe, and at the time I didn't think the cost was worth it.

I believe my viggen has the eibach pro kit. I think it sits just right. I would say the ride height difference from stock is 1.2 front 1.0 in rear.

Eibachs need to be imported ? since when ?

I think im just goin to go with a 50mm drop front and rear. But i do know what you mean the stock ng springs are already short shave 1.5 inches off you have little amount of spring.

50mm is nearly 2 inches... If the vogtlands are 35mm, your going to need to run some skinny tires up front or remove the wheel well liners and roll the fenders if doing 50mm of drop.

You could always go the custom coilover route... Race / Sport Coilover Kit 9-3 99-02, GenuineSaab.com

Here are some pics of my NG with vogtland/konis, 17x8 RKs and 225/45/17 tires.
