First shown to the public at the 2002 Autosport International show in Birmingham, the Radical SR3 is one of the cheapest ways to go extremely fast. Originally aimed at the third of three divisions of the FIA sportscar championship, the SR3 can be used as track car or road car. An immediate hit, it was named 'Trackday car of the year' by Car Magazine.
The chassis is simple, but very efficient steel spaceframe, that offers plenty of rigidity at a very low weight. It is suspended by double wishbones all around, double damper units are available as an option. Braking is taken car of by vented discs, with cross drilled units available as an option. The fiberglass body adds next to nothing to 495 kg dry weight.
Installed in the spaceframe chassis, is a four cylinder motorcycle of various makes and sizes. The least powerful of the five engines available is the 130 bhp Kawasaki 1100 engine, with Suzuki's 1500 cc engine as range topper at 252 bhp. Mated to the engine is a sequential six speed gearbox, which allows lightning quick gearchanges.
Performance was better than expected and the SR3 started winning all across Europe in its first season. Road legal versions proved their worth in various road tests. On a damp Top Gear test track the SR3 beat the Pagani Zonda's best time, recorded on a dry track, by four seconds!
The featured SR3 is seen here on the Spa Franchorchamps track where it took part in the five hour endurance race, which was part of the RMU Classic weekend. Overall victory in that race was had by another SR3.
"This car is a track day legend, all the motoring journalists and racing fans alike have nothin but praise for this car! I cant beleive that this car is road legal!!(in the UK anyway), according to EVO magazine this car has a 0-60 time of 3.1 secs!!! and depending on spec u can getta sub 3 sec 0-60 time! For a long time Caterham has been the king of track day cars, now we hav a new challenger in the form of the SR3, this car takes the ""turn-up-to-a-track-and-drive"" game to a whole new level. When it comes to lightweight low price specialist sports cars the british rule!!"
you should know better !

"the basic car is ""cheap"" to buy, may be fun to drive and have a great look, but that's it look at the options list, it's f@&^$= options which cost a lot of money and needed to run the car ! fe you need the cooling system for the SR3 gearbox otherwise gearbox failures and please don't buy the tuned 1500 engines.. bang... told ya... if you want to spent a lot of money to race/run fine, because that's just what you will be needing spares are short lived, especially suspension and hub carriers (by manufacturer as an excuse to protect himself from failures)they're the last to blame if you find yourself in a wall ever looked at a zeus challenger instead"
Just A Silly Car
More power than a family turboed car, As light as a go-kart, can change direction faster than a fly. This makes the car very very dangerous on a track. I would love to see the face of a Ferrari driver as this just flies past it with no trouble at all. Just mad.
