If it's as advertised.
If you have a smaller pulley in the alternator/fan you get higher fan speed or are you referring to smaller crank pulley?

Check this one out; it’s in Portuguese obviously coming from Brazil but it looks like a very interesting proposition. It adds rack and pinion steering as well:

Looks a lot like the Imohr kits, also out of Brazil. Unfortunately, it did not fit in a Spyder, just not enough room.
Ideally, the A-arms on a wishbone suspension are unequal lengths. The arms on a iMohr (and Medeola, and Red-9) front end are all very nearly the same length.

Stan is absolutely correct. The only way this is happening on a Speedster or Spyder is with a complete front chassis redesign.

... like Beck did with the new Speedster chassis.

I'm assuming that A-arms that are close to equal length will result in too much camber change when compressed compared to considerably different length A-arms? \

I believe that you want the camber change as it keeps the outside tire's contact patch at a better angle - assuming the long arm is on the bottom, of course.

THAT ^^^
You definitely want slight negative camber when at static ride height, cruising down the road(least rolling resistance). The slight negative camber is for turn-in bite. Especially on a VW beam, as there is ZERO camber change with suspension compression, so you want MORE than stock VW camber if you have sporting inclinations.
When cornering, desired suspension response changes. The outside tire needs to get more negative camber(under suspension compression) so it stays relatively flat as the body rolls.
The inside tire(under suspension extension) needs to get less negative as it extends, but not go positive. There isn't a whole lot of load on it anyway.
Unequal length control arms take care of all this by design.
@Impala I think what Ed is saying about the Andrig fan is if it is more efficient it could be slowed down. He's talking about a smaller crank pulley.
What a great explanation, Danny. Thanks for taking the time.
I put my original Andrig fan in the trash. It seemed to be noisier than the original fan and the hole in the plastic center was breaking away a bit.

I remember reading that he had a problem with the first run with the centers. He later devised and offered a free retrofit for those customers; some type of a metal center adapter.

Oops, I misspoke. Equal length A-arms will not change the camber when compressed, but unequal A-arms will change the camber. Thanks for the correction DannyP.
