Around 80 MPH the car has tended to want to "shift" less, and feels slightly more grounded. The rear end seems less twitchy compared to just a front splitter/stock diffuser during this weekends canyon drive. So I highly recommend any diffuser improvement if you have front aero done. The windnoise above speeds of 45mph have decreased significantly compared to stock diffuser/exhaust exit.

The product looks very professionally made and came to me very well packaged. Much better than expected from a start-up company. Glenn has also been a pleasure to work with, the diffuser was shipped very quickly and he's stayed in contact with me through-out.

The Difflow diffuser is a work of art. If you are in the market for an aftermarket diffuser, get a Difflow. The alignment of all the holes was better than factory.

I have an 05 Elise, that is N/A with no front lip or other ground effects, and has the Sport suspension set up. Got home this weekend from a trip to Idaho, and went to work sunday night at around 10:30pm and had the whole thing installed by 11pm. The fit was PERFECT, you could tell there was A LOT of care and detail that went into making the diffuser. The construction is VERY solid, I personally feel the factory diffuser was a little on the weak flimsy side, but the quality is TOP NOTCH!!!

I had JUST driven my lotus on a 1000 mile road trip this weekend. We hit everything from cross winds, to sunny weather, to dry heat, etc...and this was before I put the diffuser on. I mention this because this will let you know that I had a VERY good idea of the performance benefits I have felt from the new diffuser, since I just drove the OEM set up the day before. The crosswinds had me ALL over the road (I say this in comparison to what I experieneced today), and the cross winds were about 20 to 30 mph...so they were pretty intense.

TODAY, After the installation of the Difflow 7 element diffuser was a COMPLETELY different experience. I drove the lotus into work, and trip that I have done many a times before, and the experience was COMPLETELY different. Going to work I had about a 30 to 40 mph wind coming in from the west. This breaks down to a tail wind for the first 30 minutes of the drive and then a nasty crosswind for the last 15 minutes as I follow a river right through the valley. They car handled AMAZINGLY well. I was LITERALLY driving the car with just 3 finger tips and a thumb tip and wasn't even working at it, and I was doing speeds from 60 to 90 mph. When the freeway openned up, and I had the chance, I wanted to see how it felt at faster speeds, and lets just say that at "Spirited" driving speeds the car was ROCK solid. It didn't flinch, sway, or hiccup in anyway. My friend who was with me wasn't that impressed (he had never driven with me to work before so he had nothing to compare it to), BUT when I took a 30 mph offramp at 65 mph and then a 90 degree turn at about 45mph or better the statement out of his mouth was DANG!!! The car just freaking HOOKED UP!!! (He had been with me on some twisty roads before).

He was right, on those two corners my car has twitched a little bit or "hopped" a little because of the road condition, however today the car stuck SO WELL that it was ridiculous at how much more confidence such a simple addition did to the handling performance of my car.

So I must say, that if you have been riding the fence on a Difflow Diffuser, PLEASE don't hesistate. The diffuser where it has great looks is VERY VERY VERY functional, and it does its job SO WELL, it is RIDICULOUS!!!! I also realize that the pictures actually don't do the diffuser justice, because it is not NEARLY as "Agressive" looking as I thought it would be (i.e. HUGE). This is larger than the original stock, and does stick out further than the original stock, but everyone who has seen it, agrees that it looks great. (Even my WIFE said it looked good...and trust me that is a VERY hard compliment to come by).

So Seriously, Give Glenn a call/Pm/Email the guy, because you are MISSING OUT if you have been debating.

THANK YOU AGAIN GLENN!!!

I finally got mine today, it took me 10 minutes to take off and 10 minutes to put the new one on (by myself) and without lifting the car. Perfect fit and amazing craftsmanship, better than the OEM!!!

No track time yet but I didn't notice any additional understeer in the first few test drives on the local twisties. Hopefully I can decide on a splitter soon. Much thanks to Glenn in his excellent customer service!

I got the diffuser Friday and got it installed in 15 minutes. Looks AWESOME. I am also running a large custom motorsports wing with some fabricated adjustable height stands. Based on some very preliminary runs, it looks like the wing is grabbing more of the clean air generated by this larger diffuser and it is actually beneficial now for me to take the wing height all the way down to it's lowest position. Greater downforce with less drag, and a wing closer to the body line of the car doesn't look too shabby either

5 Element RAILER w/ exhaust hole

I got my Railer yesterday, it installed like the stock dif and had it on in about 10 mins. I have my Ohlin's set fairly soft due to the back roads that I run on. I can feel the car being sucked down at around 90 mph. I normally only go to 120+ on nice roads, but I thought I would try it and got up to 129 on a bouncey back road with complete confidence compared to without it.

I'm sold and now a proud owner!

7 Element RAILER

It finishes the aero package nicely: Railer + Reverie CF Exige Splitter + Reverie CF Canards + Reverie 1650 mm wing). The Railer weighed in 12.6 lbs versus 6.4 lbs for the stock diffuser. I've lowered my ride height by 10 mm, so the railer is 4.25" from the ground. It's still very driveable. I have a 3.5" lip where my driveway drops off to the city street; it takes care but I can clear easily without scraping.

5 Element RAILER w/ exhaust hole

Just mounted my railer 5 element diffuser to my cup car today. It looks great and the fit was perfect. The overall diffuser is much stiffer and more stable when mounted. Ran the diffuser at the track this weekend and really liked it. It seemed to improve high speed stability and made the car feel more hunkered down. It certainly drew a lot of comments.

5 Element RAILER (CUSTOM) w/ exhaust hole

Glenn form Difflow was nice enough to make me a custom 5 element railer diffuser. The quality of his work is exceptional, and he was able to build it to my specs exactly as I requested. He also provided excellent customer service with updates. I call it the railer jr.

Todd from Wexford, PA -- 2010 Graphite Gray Evora.
7 Element (first ever, prototype Evora diffuser)

So wrecking the car ended up being not too bad of a deal afterall. Glenn from Difflow offered fabricate a new one for me and look what he came up with!! I still have to replace the diffuser finisher, but wow it looks awesome! The build quality is top notch and the whole thing is very light. I don't have a good "before" pic for comparison, but this looks just right for the Evora! Maybe if I would have had this in the car prior to my accident the added downforce would have kept me on the pavement.

John from Hawthorne, CA -- 2006 Lotus Elise with VFII Supercharger.
5 Element RAILER JR.

Glenn, Thanks for the quick response. The car definitely feels more "solid" above 50 mph. SouthBay AutoHaus did the install, along with a VF II supercharger and VF muffler. It is now a completely different car, in a good way.

You do nice work and your service matches, always refreshing.

Was on my way home from the 13hr headlight brigade race at VIR last night when I took on a sleeping deer in the middle of the highway. My headlights are aimed low and I didn't have enough time to swerve. I thought for sure my front clam was going to be mangled, but thankfully it wasn't. It made one heck of a bang though! Check out the diffuser, sharp as a knife! Must have cut that deer like swiss cheese. I kind of wanted to go back to see if the deer was sliced into several pieces then wondered what the deer would have looked like if I had the 5 or 7 element.
