Pretty much a straight fit. Just had to drill a few holes. The X-Ray foam bumper is slightly thicker but fits and looks good.

Well first practise and bent a front driveshaft and snapped a c hub and knuckle from a Tiny tap..

Although it did withstand 2 massive crashes after that.

I don't think the xray bumper is any bigger than the stock bumper. it's just firmer foam.

I've been testing with a front diff in the USGT car to improve turn in and tire wear. We always run a sweeper on or off the back straight which is hard on the fronts.

I started with 10k and that seemed to help turn in but I was loosing some punch off the corners. I went to 100k then 300K to gain punch off and still keep the good turn in. I didn't see much difference between 100K and 300K. Lap times were the same. Punch off was lots better. Front tire wear seemed more even with the diff. The spec USGT tires are directional but I see no difference in handling when rotating the front tires.

I also have been experimenting with rear diff fluid. I tried 1K, 2K and 5K. 2K seems to be the best. 5K made the car a bit loose off the corners. 2K has a bit more on power steering than stock 1K.

Bodies now are being tested. I found the Tamiya BRZ Scooby Doo the best so far. It has a huge front splitter. The stock wing has been tested and deemed useless. It has been replaced with a Proto Camaro ZL1 wing and standoff.

Good luck and report back.

I think either one will work.

OK I'll see if they will ship to the UK.

Has anybody got the part numbers for the trf driveshafts which fit? These seem to be made of cheese.

Default Front bumper

Unfortunately there are no ready made bumpers that offer max durability. Most offer front straight on impact protection. For best protection you have to fab a Kydex and a Parma foam bumper. This combo will do the best for front suspension and drive-train protection on corner impacts.

Below is the best protection possible. A Kydex base that is 190mm(to be legit in Sedan) wide and a formed to body Parma foam bumper glued(E6000) to the Kydex. I also replaced those 4 short screws with 2 long screws and lock nuts to tie it all together.

It takes some time to do this correctly but you be rewarded with less frustration and fewer broken parts.

Hi,

Sorry for the delayed response. Part # is 301223 or XRA301223.

I found mine on Ebay but Amain or TQRC racing has them. They are slightly thicker than the H4 stock one but they do fit. I tried a Kydex type of bumper first and it kept flexing up and still got broke parts.

I just noticed the glueing part from the post above and I did not glue my Kydex type piece to the foam bumper. That would make all of the difference for durability. For now I am satisfied with the Xray hard bumper.

Hi,
Did you test on asphalt or carpet?

No asphalt racing here in Ohio in the winter months. Prepared asphalt should have similar results with good tires.
