Finally got the coilovers and top mounts on, just set them up with a tape measure for now but will get the car set up on corner weight sales at some point. Just going to let it all settle in for now them will redo the wheel alignment but first impressions are really good, on the road with the bump and rebound on the softest settings it rides better than the ZR/ZS dampers i was using before. Should be back at Bedford Autodrome in January to test them with the MG/Lotus owners club see if its all been worth it.

Had the cut most of the inner sections of the turrets out to get the -4 degrees as in the Rover Sport manual as per Dunlop Cars but think i will go for -3 degrees when do the alignment again.

Little update ive decided to throw the rear trailing arm Poly bushes in the bin as im not happy with them, main reason being is there so hard i am unable to adjust the rear toe angle and as they were both towing out slightly im sure that was one of the reasons was having trouble on track keeping the rear end in check. After a lot of looking around online and talking to people racing Honda's here and a few in the USA ive gone for PCI spherical bearings which are designed to be lowered and offset in the trailing arm to correct the toe angle etc on bump steer. Was a costly move as they are only available from L.A in the States at $260, $35 shipping then £36 duty to the queen. Must say im very impressed with the quality of the parts and the suspension moves so much freely now when you push down on the corner, compered to the side with the Poly bush in its like having to completely different springs fitted. I also noted that you hardly get any change in the angle of the wheel when you add weight or jack the car up slightly where as with the poly bushed side its quite noticeable so fingers crossed its looking like when a worth while, even tho expensive upgrade....

Finally made a start on the new gearbox today since i had a day off work, been looking for a good low mileage G4BSV PG1 from another ZR160 but been unable to find one so ive decided i will use the G6BP box i have as a spare i got from a Lotus Elise S2 111S as i know its a good low mileage unit. Its the same low ratio 1st-5th gear set as the ZR160 but with the 3.9 diff rather than the 4.2 i want so im also replacing the input shaft and crown wheel to bring it to the same spec as the box already in the car. Just doing a dummy build for the moment so i can measure everything and order all the bearings, shims etc all together cant wait to test the ATB....

Just quick inform, done a trackday yesterday at Bedford again to compare the car against how it was last time. I will be making a little video of my best lap from this and last trackdays side by side for comparison I'm just waiting for Javelin to add the pictures so can made a little video but i was just over 7 seconds (best vs best) faster than before since fitting the coil overs and PCI bearings which is two corners on the track so I'm on the right path. Still a long way to go but so next things are to double the spring rates (still to soft for track) and definitely need to get the LSD in as I was getting terrible wheel spin out of corners so was having to often say in a higher gear which is probably losing me a few seconds per lap but here's a little drive by clip filmed by someone in the pits....

Quick update, been a bit of a delay as i ended up not using the used diff i had a got a brand new unit ATB from Quaife but i had a bit of a nightmare getting a few of the shims i needed due to them being obsolete. Anyway its all rebuilt now and back in the car with steel caged bearings and all end floats ect all set to factory specs and filled with Millers Nanodrive CRX 75W90 NT+ competition gear oil....

A little cosmetic update for change since ive got no new parts to fit :unsure finally got round to doing a job thats been bugging me since got the car. It have various rust spots on the drivers door where i would guess its been opened against something and knocking the paint off so thought i would address it now before they become holes....

Took it down to metal to grid out the rust....

2019-03-31_08-14-02 by John Quincey, on Flickr

Then i put on some rust treatment, a good coating of anti rust primer and a coat of high build primer followed by a flatting off to smooth the surface....

2019-03-31_08-14-50 by John Quincey, on Flickr

Than the top coat, unfortunately i just used a tin of the Halfords paint so the colour match is a bit off (to light) but im not to worried as its not a show car just glad not to be looking a rust every time get into it :tt2 .....

Another little update since its been June/July since the car has been started or even moved :S I decided to let the little Rover have a break over end of summer and put the Evo on the road for a while....

Any way back to the R8, made a few changes to been it into line with the regs for the race series i want to run in. The major one is the fact i have to run the factory size wheel from the range so shes finally back on 15" wheels :D ....

That being said brings a few good points, looks better and i can set the car lower but the on the negative side means i cant run the big brake kit so im down to ZR160 282mm discs and calipers :scared Im also going to have to use the 216 GTI wheels (which are heavier than the 17's) because the Turbo wheels rub on the 160 brake caliper carrier. Back on track next month with this set up and stiffer coil springs for a bit of test time to see what happens :tt2

Little update to the thread, so over winter made a lot of changes to the car. Those being stiffer springs (up by 100lbs front and 120lbs rear over the old ones) change to the ride height which was the main reason for going to the Rover Sport 15" wheels, going from the 330x28mm discs, 6 pot calipers and DS3000 pads to MG ZR 160 282mm discs and calipers with Carbotech XP8 race pads, changes to both axle Toe and Camber settings, a G code gearbox with a Quaife ATB diff. So anyway on the 9th i finally got to get on a Trackday with MGoT to see how it all played out. I must say i really wasnt sure what would happen after making so many changes all at once and more less starting agian but im pleased to say the car handled amazing and the transformation in the traction was unreal. With the open diff last year on MGOC Class A Dunlop full slicks i got no end of wheel spin but with the ATB on thinner road tyres there was none. Thats all for now until the next change or trackday....
