I'm looking for some feedbacks on shifter risers:

There are two options that I'm looking at:
Option 1: Rennline 4" shifter riser https://www.rennline.com/Shifter-Ris...fo/I32/SILVER/
Option 2: HRD carbon fiber shifter riser http://www.function-first.com/produc...er-shifter-box

It would go into my 997.1 C2 with Numeric Racing shifter already installed. The car is still a street car so the e-brake needs to stay.

Here are my thoughts on them. I saw some posts with people running the Rennline 4" shifter with the e-braked intact. But I'm concern about the rigidity of the riser, due to some people claiming that there's side to side movement in the riser when shifting under load. I even saw a person selling his/her modified riser with a brace to prevent the flex.
As for the HRD carbon fiber shifter riser. I can't find any info about it other than the product page from the vendor that's selling it, Function-First. I was told by the vendor that it would work with the e-brake, if it's raised by by their e-brake risers. It would be nice to get some confirmation on that from end users.

Any input on these risers would be greatly appriciated.

 

I've ordered a HRD box, will share my experience here:
