I purchased a set of pedals for a Lotus Exige v6, with the objective of improving the pedal position to better suit my ergonomics, & improving the consistency of heel toeing on track.
I have been very impressed with the quality of the product, both in terms of material used, & the skill of the machining (it is nice to see products of this type continuing to be made, as machine shop engineering sadly slowly seems to be becoming a bit of a lost art). It should be noted that these are nicely machined replacement aluminium car pedals, rather than some form of more cost effective thin pedal covers or extensions.
Having fitted the product, it has successfully reduced the space between the accelerator & brake pedals, which for myself has improved my ability to "blip" the throttle consistently when heel toeing into corners on track. There is a level of adjustability in the pedals (basically a number of mounting holes that can be used), that I imagine would allow the pedals to be mounted in a suitable position for most "average" sized people looking to improve ergonomics.
I should also note that the pedals were shipped from the US to the UK, within a very reasonable cost & timeframe. Having initially looked around & been unable to find a high quality local solution, it was very handy to be able to import the pedals from across the pond. On a separate note, the quality of the instruction sheet (providing guidance on how to mount the pedals, &, unexpectedly, the different methods of heel toe) was also very good, & showed a genuine knowledge of the product being sold & the related skillset.
Overall I would happily recommend this product if looking to reasonably adjust the ergonomics of a car pedal set up to help with heel toeing, or similar purposes.
