F1R3 Performance Evolved.
The next evolution in the Exotek F1 line of chassis for the F104 and F103.
With countless hours of testing, engineering and prototyping, we bring you the penultimate F1 chassis.

- New side ways battery mounting option for increased rear grip and the reduction of the rear tires 'diffing out' on carpet tracks.

- Also allows normal 'inline' battery mounting for quicker steering transistion.

- Lipo strap 'posts' are shaped to snugly hold your standard shorty lipo pack in squarely and securely. Special cuts in the posts allows your esc or servo leads to pass through for a tidy layout.

-'Hybrid Link' side link suspension integrated with a flex 'T Plate' chassis. Using both types of suspensions in one platform means the F1R3 practically glides over bumpy surfaces without sacrificing the responsiveness and tuning of a link suspension. Superb for rubber tire racing!

- Rear pod geometry for more progressive dampening which increases forward bite.

- Twin side dampeners for equal left and right pod damping. Smooth machined POM inserts for silky smooth damping. Compact ball end design allows for extra suspension movement.

- Design optimized for 'shorty' lipo packs.

- Quick adjust shock end for on the fly pod droop adjustments.

- Quick position alloy servo mounts. Allows for quick and easy Ackerman tuning as well as servo mounting without the need for servo tabs removal (low profile servo required).

- New US made premium 2.5mm quasi weave carbon fiber is used throughout.

- Angled side links. The triangulated angle improves suspension geometry resulting in much freer rear pod movement at extreme left right angles. Also a 2nd position is allowd for 'straight' links for increased mid corner steering.

- 2 wheelbase option rear pod design. It only takes 6 screws to change the wheelbase from the standard long F104 or the shorter F103! The short wheelbase is a great tuning aid for small indoor tracks! Long wheel base equals 269mm. Short wheelbase equals 263mm.

- New v2 precision machined lightweight motor plates. The right side insures secure motor mounting with heat sink performance while the left side allows for mounting of a fan for motor cooling. The rear pod includes spacers that allows for high or low axle height to match F104 and F103 tire heights.

- Alloy side spring nuts for easier side spring assembly and tuning.

- Includes Associated side pod springs. These are used to tune for steering response and pod level (tweak).

- Lghtweight but heavy duty nylon body post set included.
- Bonus- the front of the chassis is designed to accept the Exotek IFS suspension proven to be outstanding for cornering. Now available!

Compatible with and required- any Tamiya F104 or F103 kit

Also required:

- PROTOFORM F1-13, F1-14 or similar wide F1 body (Xray F1 body). NOT Protoform F1-15 or Tamiya bodies which are too narrow.

- Rear wing mount (unless you have the F104v2)(OK - Tamiya 54375, Tamiya 51479, Exotek 1376, Tuning Haus 1001, etc)
- Dampening lube (example CRC blue or 10,000 weight silicone)
- Tamiya TRF damper #53901 (if you don't already have this)
