I suspected all the above, thanks for clarifications. Yes, I am used to seeing on Porsches and other cars. With that being said, these are certainly somewhat fragile areas of my SR3XX fenders as two...

@raider89, Spring Mtn also makes a screen that you attach to the underside of the louvers. I can't recall the cost, but they are not expensive.

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...

Well this is not good news! If you remove the clutch slave cylinder (near the output coupling) and take out the pushrod what does this look like? I would assume that it has been 'machined' short and m...

I put the sand bags on top of the car just behind the crash structure. Between the front tires. No problem on the measurements. Let me take some new ones, I think I threw my original drawing out. T...

@charleyhradicalsportscarregistry-com that’s the one. Team Stradale is doing some refreshing so I’m ready for some track days. If anyone is a driver club member for VIR or Summit and wouldn’t mind a g...

Hi fellow Radical fans, After my last Silverstone trackday in Nov, I heard a rumour that Silverstone were changing to a more 'corporate style' venue and would no longer be offering the track for 3rd p...

Hey guys, I'm putting together a group of friends to rent Road America privately for a day next summer. We've picked Friday July 22nd because it's right before the EAA air show that some pilot friends...

@rojid There is definitely no need to buy a spare compressor unit. As others have also said I have never had any trouble, and I haven't heard of anyone else doing that either. The normal issue that ...

Aw, nobody here wants to see a bust Radical 😪 Listing a little old, but you might get lucky

Hi John. (Every thing has a price) the chassis has been rebuilt frame wise if you have a spyder you could swap the parts over quite quickley i have collected quite a lot of parts to rebuild it ie up r...

@charleyhradicalsportscarregistry-com That sums it up very succinctly!

G'day Dan, I recently replaced my 1500cc Long Stroke engine with a brand new unit from the factory. While I was refitting the headers I noted that there was some areas where they were close to other...

Thanks Charlie, I had it in my mind they were 1" and couldn't see the size on the side of the cylinders.
