WR35 GTR Performance Parts



WR35SP GTR Front Splitter

NOTE: WR35SP IS NOT AN OFF THE SHELF ITEM. IT IS SPECIAL ORDER AND MAY TAKE SOME TIME TO PRODUCE. MINIMUM ORDER QUANTITY IS 5 x PIECES GTR Front Splitter on Car

The Willall Racing WR35SP front splitter is designed as a complete modular aerodynamic upgrade for the nose of the R35 GTR. Coming complete with a heavy duty mounting system that locates in existing holes and able to be installed with zero cutting to the body WR35SP gives noticeable high speed balance and reduced understeer for all GTRs, and particularly those with an upgraded rear wing.

GTR Front Splitter

WR35SP Splitter is crafted from ¼ inch thick Polyethylene plastic which is a great colour match for the GTR lower lip giving great visual integration. The splitter protrudes just under 3 inches from the nose of the GTR and is able to give performance improvements of 0.2 – 0.3 seconds a lap in a typical 1:12 lap time. As a true DIY fitment and removal, with replacement splitter blades available should you damage one WR35SP makes a lot of sense for the GTR track enthusiast!




WR35TSP TRUNK SUPPORTS

One thing that frequent track-goers notice is the amount of movement that is in the GTR trunk-lid in the downwards direction on the back edge, particularly with an aftermarket rear wing in place. Go push down lightly on your wing (even if its factory) and the rear edge of the trunk lid will deflect up to 1/4 of an inch downwards. This is no good when trying to load the car with a wing for steady state down-force - and the culprit is this factory piece, a structurally weak trim clip as pictured here -

We then set about designing and machining a fully adjustable and structurally strong replacement part, manufacturing it from black Acetyl and mounting it securely to the trunk lid with four rivets. The pad is larger, the structure stiffer, and when fitted into place and adjusted correctly the trunk lid wont move....at all regardless of the downforce applied at the back edge

Here is the fitted and finished product. While the gains from this type of improvement would possibly be minimal it’s approaching race car engineering from the '100 cents in a dollar' perspective and that achieving every last small improvement nets a big improvement. We certaily felt it was worth the investment in time and tooling to produce for our own tracked GTR. Note race teams go to a lot of effort to stop their trunk lids deflecting....
