Hey guys,

just wondering, are there issues with running two brands of semi's?

I posted while ago bout my dunlop direzza's - 2 are just about dead, but the lhs are still really good.

Now ive got my old r888's in the garage, and the best 2 out of that set, are better than the 2 dead dunlops currently on the mxfail..

they are the same profile/size etc.

would there be an issue running the two brands?

say dunlops on left, r888's right?

or would it be better somehow to have the dunlops up front, and r888's rear?

discuss! :thumbsup:

it will be just for the next supersprint @ OP GP in august, then its brand new semi's :3some:

cheers,

Chris

I can't speak for the Dunlops or toyos, but I know you can run the A048s in the opposite direction to what they are usually run... I'd Imagine that it wouldn't be a problem with these either which would allow you to match brands front and back...

But best wait for an expert's (aka Gary et.al.) advice.

never run different tyres on the same axle, least of all semi slicks. You will end up with some difference in grip side to side which will stuff you every time under brakes

No problems with different tyres front and rear, its done all the time.

You will be fine to swap sides as long as the tyres are not assymetric, pretty sure only bridgestone are. no problems with them being directional (one rotation direction) to run them on the other side just mount them on the rim the other way, ie turn them around 180o

Cheers uncle Duncy!

I shoulda just called you first of all :D

Thanks chris and axe also!

Duncan - with these tyres, and my car...what would you put up front and on the rear?

It depends on whether or not you want some understeer or oversteer. My guess is the Dumlops will have more grip than the Toyos, but if they are past it then that may not be the case.

Sorry to hi-jack, but what about rotating front to rear (same side). Assuming moderate and even tread wear on some RE55s - same all around. I've got a little scrubbing on the fronts so hence the need (a little driving style and a little set up related)

yeah I rotate front to rear all the time.

basically if you are lucky enough to have same size front and rear, and are not using assymetric tyres like Re55s you can put the tyre on any corner of the car. so we actively manage them at each race meet to even out the wear as much as possible. 4wd is great for this but most gtst run wider tyres at the rear.

      Initially I thought having a pair of Recaro seats would be a big bonus, it turns out these do get a little uncomfortable on long journeys (my fault, not the seat). I had a look through the GSM Performance website at reclining seats and booked an appointment to visit their show room. I got the Recaro Sportster CS for the R34 from here, was very happy with the service received so of course a re-visit was in order. Unfortunately the two Corbeau seats I had chosen aren't on display but they had 4 other options available. Two seats dug into my back, one dug into my legs and the other was perfect. I also found out that Recaro seats use a larger bolt pattern so some adaption was required. Luckily GSM offer some universal adaptors that should solve this problem. I searched the interwebs for price comparisons and Corbeau themselves were the cheapest at £300 cheaper (for the pair). I asked GSM if they could price match, unfortunately they couldn't. I later received an email saying Corbeau would honour them the same discount, but the purchase was already made. I did however order the brackets from GSM, both arrived on the same day. I started with the passenger side seat, knowing this was going to be a little trial and error. There are 3 mounting holes at the front and 2 at the rear on these JURAN Racing seat rails.  With the adaptor brackets mounted, the allen cap bolts started to push into the seat, NOT GOOD!  The rear mounting holes lined up but there were issues at the front. The holes were 1/2 hole out, so the brackets got a tickle with the drill to modify the holes. The supplied bolts weren't going to be long enough and a spacer was needed to stop the adaptor bars from bending. A local fasteners company supplied be with some nylon spacers and longer bolts (M8x30, although these will be replaced with 35mm long shortly) A before and after I pre-drilled the front bracket before making a start on the driver's seat to save some time. And in no time at all that was in the car too. The all black seats have transformed the interior and these are MUCH more comfortable. The only downside with the new Corbeau seats is I sit a little higher, but I'll happily accept that over discomfort. The Youtube video can be found here: https://www.youtube.com/watch?v=wPyttKPktXA

      All 3 I guess. The car came with the JASI Aero 4 door Type R Full Kit unpainted so this was one thing at the top of my list to complete then I noticed there were body panels parts for this kit so i picked them up along with some black mesh to fill in the front bumper and front side air vents. car is at a paint and body shop atm completing this work. Next I will be addressing the internal bells and whistles, great summer project I can do with the kids.  full interior removal - ,boys car sound deadening - pads and spray ,boys stereo, sound, lighting - Big 3, GTT or bigger alternator ,kids head lining - dye black add star lighting mod ,daughter. That's it for the next 5-6 months. I have some motor maintenance  work i have to plan out. oil filter relocation, gaskets, mounts. beyond that, mind is starting to turn over if i can use a DET intake plenum, block off turbo ports & pipe in a air intake.
