how much room do you have between your front wheel and down tube?

I'm moving this to Mechanics, and leaving a trackback for anyone that wants to answer from Road.

If the two forks are equal length so the front of the bike is not raised or lowered, the steering will be slightly slower with the shorter rake fork. Not a "problem", just slightly different. Most people don't notice a minor change like that.

I agree the change will be minor. Less rake gives more trail so the bike's turning response will be a bit slower and the straight-line stability a bit better. In both cases, the change will be small.

There is no such thing as "ideal". The offset or rake affects the amount of steering trail, but so does the axle to crown distance, since it can change the HTA.
The short answer is you might get about a 2mm increase in trail that slows the steering a bit, but that's only if the A-C length is the same. If not, you might get no change or more than a 2mm change.

I replaced the 43 mm rake offset Ouzo Pro fork in my 5500 Trek with an otherwise identical 40 mm rake offset Ouzo Pro. I could feel a difference immediately but the difference was fairly minor and the bike now feels a bit more stable. There were somethings I liked better about both forks. The 43 mm let the bike move laterally quicker, could be better for criterium racing. I decided that I liked the straight ahead stability of 40 mm better.
