I'm pretty sure I am going to go with the Vogtland's. One question I have is if I wanted to transfer them to a B5 S4 from my 98.5 A4 would I need any other parts? Noticed that they have the same SKU/par # on the PureMS site (968417). What other Coilovers are the Vogtlands compariable to. I have already read the H&R Ulrta vs. Vogtland CO's thread in the archive.

the best one is think is s4madman's...

You're comparing a 400lb spring setup to a 600lb spring setup.

They're similar in price only, not much else really. The Vogtland's are considerably more firm.

It's a firm coilover setup that works well on both vehicles.

Comparing spring rates, you can get similar rates with the Stasis Tracksport setups or H&amp;R Ultras.

They're a great setup for daily driving and spirited track events as well.

looks like I'll be going with the Vogtlands then. Most likely going to buy them in mid April. How long do they stay in stock for you? Startup Racing has them on backorder and noticed that when Tomasz gets them in stock they go quick.
