mounted my railer 5 element diffuser to
my Exige 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." Edward from Newark, DE
did a total of 20 runs, 13 of which were
over 200 MPH at the Texas Mile in our Nissan
GTR. The diffuser felt very solid. The front
splitter ripped off the car and went underneath
and the diffuser chopped it up into 4 or
5 pieces! We were able to achieve the 2nd
fastest top speed in the world with our
SSP GTR - thanks Difflow!" Jeremey Rohrs, SouthSide Performance,

Will a Difflow diffuser fit on my Lotus?
We carry diffusers that fit on these models:
2005 Lotus Elise
2006 Lotus Elise
2007 Lotus Elise
2008 Lotus Elise
2009 Lotus Elise
2010 Lotus Elise
2011 Lotus Elise (WILL NOT FIT) -We have made
diffusers for this model. Email us.
Our diffusers are a direct OEM replacement
- no drilling, cutting or modifying anything
on the car. Fits with all aftermarket rear
panels and eliminator kids. Works with all
you make diffusers with an exhaust hole cut-out?
your Elise/Exige has an exhaust that exits
underneath your diffuser, then you can order
a diffuser from us with a hole cutout. On
the order page, you will be asked if you need
a cutout or not. Cutouts are big enough for
a stage II and Oval tip exhaust. If you want
to cover up your exhaust hole cutout, then
you can purchase a coverplate here.
What diffuser is right for me?
diffuser we offer provides a sufficient reduction
in drag and increase in downforce. Styling
is up to you. The best diffuser would be a
Railer or Railer Jr diffuser, because the
fins aren't curved as much as the original.
Curved fins let the air spill out sooner,
which is why squared fins perform better.
Will the diffuser scrape on
the ground and over bumps/hills?
We built them to sit at an appropriate height
to avoid scraping. Here are the clearance
measurements for our diffusers on stock suspension.
Lotus Elise, Exige:
5 Element Rounded - 5 Inches off ground, parallel
5 Element Railer Jr - 5 Inches off ground,
parallel to surface.
5 Element Railer - 4 Inches off ground, parallel
5 Element - It's not any lower than your OEM
diffuser - sticks out 3 inches further in
7 Element - It's
not any lower than your OEM diffuser
- sticks out 3 inches further in rear.
Remember that these measurements are taken
on OEM suspension. Always proceed to inclines
and bumps with caution. If the front of your
Elise/Exige/Evora clears an incline or bump,
the rear should too. The RAILER is the only
diffuser that may scrape.
How difficult is it to install
unbolt your current diffuser. Save the nuts
and bolts because you will be using them again
to install your new Difflow diffuser. Bolt
on your new Difflow diffuser and you're done.
Takes 15 minutes.
Do you provide instructions
and hardware to install the diffuser?
we provide instructions. No hardware required.
Use your OEM nuts and bolts.
Do you provide the rubber edging
that was originally on my stock diffuser?
diffusers do not come with the same rubber
edging that the factory put on your stock
diffuser. It interrupts the airflow of the
car. Some of our customers use ''door edge
guard'' or ''door edge trim.'' You can buy
it at any autoparts store and simply put it
on the fins/body of your Difflow diffuser.
Here is an example.
How long does it take to receive my diffuser
after I order it?
the diffuser is in stock, we usually ship
on the same day. 48 hours at the most. If
we are out of the diffuser you ordered, then
we take aprox 1 week to build and powder the
diffuser. Once everything is done, we'll provide
you with a tracking #. We ship FedEx ground,
but we can ship faster if needed.
If you have any more questions, pleasecontact
us and ask.
