@rjbender, when I got my first SR3 it had 13 hours on the engine and the time on the GDU was unknown. I was told by the seller that it likely had similar hours to the engine. At my first GDU oil cha...

I will guess that the louvers serve as a vent to release air pressure in the wheel wells which would otherwise create a lifting force, reducing downforce, thus reducing traction. That said, I know an ...

Yes, the wheel wells develop high pressure and the vents are there to relieve it to better allow the underbody to do it's work generating downforce. Same vents can be found on the GT3RS, GT2RS, and G...

@rojid, some people like to have a spare starter just in case the don’t react quickly enough when they spin. I have never heard of anyone bringing a spare compressor. it is a very good practice to st...

@sr10formetoo, Sounds like a fantastic day! I agree that once you take a Radical out on track you will never be impressed by a street based car again. There is nothing like driving a lightweight, hi...

I had my 'turn-over' day(s) for my SR10 with Radical Northwest over the last two days at Laguna Seca. I have never had the luxury of a full support team in an arrive-and-drive setting. It was wonder...

My car is 2021 SR3 XX. I just noticed the passenger side header from underside of car is actually resting on this engine casing bolt (not sure what that covers). Regardless, does not look right as a...

6 seconds, nice!! Next time you are at Spring Mountain take a look at my car(s). I probably will not pick them up until Jan/Feb. I went with Race Radio on both. Set up works nicely. Post some pic...

Hi @teamlorenz, you did everything correctly. The last step in the process brings you to a “Payment” section for a $0.00 charge. It gives you an option to cancel. It doesn’t matter if you use the ca...

@raider89 It looks like these sealing washers that ANHoseFittings.com sells are an exact replacement for the GDU fittings that Radical uses. Described and linked above. Attachment : IMG_6509.jpeg...

We now have a new "Radical Parts For Sale" section on the Registry. This is a free area for people to buy and sell Radical parts. You can get to this page by selecting the "Radical Parts For Sale" b...

I ordered some 1/8" HPDE boards, will cut to size, and try this added layer for sacrificial surface. Certainly significantly less expensive than the factory dense wood shapes assuming it works well.

Posted by: @raider89 The center front diffuser pad has two 4mm hex head cap screws, but they dont want to back out when unscrewing and zero access to back side within the diffuser. The other four at...

As noted above, they are peel rivets - easily drilled out with 5/32" bit. Exact rivet from McMaster shown below. Like a dumb butt, figured out the two screws in center pad. Attachment : image.pn...

I've been using ordinary two piece RaceRamps with my Featherlite enclosed trailer with good luck. My front diffuser gently rubs on its way in, but it's not concerning. I tuck them in the trailer (long...
